You may manually assign the default gateway and the IP address and check if it works fine. Before assigning the IP address and the Default gateway manually, make a note of the IP address on the computer. To do this open Command prompt and type ipconfig and press enter. This will display the IP address, make a note of it.

To assign the IP address and default gateway manually, follow the steps below:

a)        In system tray, right click network icon. Choose Open Network and Sharing Center.

b)        Right click on Local Area Connection and click on Properties.

c)        Double click Internet Protocol Version 4 (TCP/IPv4) and assign the IP address manually.

Example: Old IP address is 192.168.0.1

d)        Change the IP address to 192.168.0.50

e)        Let the Subnet mask and default gateway be the same.

f)         Subnet mask = 255.255.255.0

g)        Default gateway, usually would be 192.168.0.1 or 192.168.1.1

h)        Click on Apply and Ok, restart the computer, and verify if it helps to fix the issue.

Hi,   If you are on a router you can reserve an IP in the DHCP settings or you can hardset the IP in Windows 7 to an address range within what the router uses.

Hah, that was pretty good. :)

This site has some more info - someone says it's not possible to change it -

http://superuser.com/questions/470585/how-to-force-windows-7-to-ask-for-a-fresh-ip-address-from-dhcp-server

Just a quick note. I don't think it's really critical to the Q&A here, but the example given for the default gateway is potentially misleading in this answer.

So, while the router's interface acting as the default gateway could be any IP address in the subnet, it does HAVE TO BE in the same subnet. So since this example is a 255.255.255.0 mask, then the default gateway would have to be 192.168.0.XXX where XXX is any valid host IP address NOT currently being used. Note that the word "valid host" in this case implies that it is NOT 0 and NOT 255.

Specifically, given this mask and the example IPs, the default gateway cannot have a third octet value of 1.

Solution: How to Change the IP Address parameter in Windows 7

Article by: Charles M. Last Modified: 2024-01-24 15:04:50

Steps on how to Change the IP Address parameter in Windows 7

This short step by step guide will help you learn how to change IP address in your Windows 7 system. By the way, change of IP in Windows 7 is easy.

If you don't know what IP parameters to change to, please contact your network administrator.

Step by Step Instructions on How to Change the IP address set in your Windows 7

NB: if you can't see "Network and Sharing Center" as above, change the "View by:" setting on the top right corner to "Small icons".

NB: For Wireless cards, you might need to right-click its icon and and click on "properties" on the drop-down menu

If you are not sure what to write here, contact you network admin

Some observations

While changing IP address in windows 7, you will find out that setting two adapters with the same Gateway IP wall cause windows to reject the new configurations. Similarly, if the change is being made by a DHCP server, windows 7 may not pick the new DHCP configuration being issued. Be sure of those before you change the IP setting.

How to View & Change Your IP Address in Windows 7, 8, and 10

You can use your computer without even knowing your own IP address, but would you like to know how to check? Here's how to quickly check or change your IP address in Windows.

Modern technologies mean that it's easy to get your devices online and not give a second thought to what your IP address is, but maybe you want to go further. If you're troubleshooting an IP conflict issue , setting up several devices on a network, or are just plain curious, it's good to know how to view your IP address and change it if needed.

In Windows, you can easily view your IP address by typing cmd into the Start Menu to open a command prompt, then typing ipconfig . This will bring up configuration info for all network adapters on your machine (such as Ethernet and wireless), letting you view the IP address and more for each one.

On a network, you can release this IP address and get a new one by typing ipconfig /release , followed by ipconfig /renew .

If you'd like to set a static IP instead being assigned one each time you connect, open the Start Menu and type Network and Sharing Center to launch this menu. Where you see Connections , click the blue text next to that (probably Wi-Fi ).

Click Properties on the window that results and finally double-click on Internet Protocol Version 4 . Here you can manually punch in an IP address that this device will always use, even after a reboot. Make sure you check the box to Validate settings upon exit so that if you put in a bad address, it lets you know right away.

You probably don't need to set a static IP for your own basic use, but it's a useful bit of knowledge if you ever need it!

How to change & configure an ip address or set to dhcp, using the command prompt in windows 7.

Not many users are aware that Windows 7 provides more than one way to configure a workstation’s network adaptor IP address or force it to obtain an IP address from a DHCP server . While the most popular method is configuring the properties of your network adaptor via the Network and Sharing Center , the less popular and unknown way for most users is using the netsh Command Prompt. In this tutorial, we show you how to use the Command Prompt netsh command to quickly and easily configure your IP address or set it to DHCP .  Competent users can also create simple batch files (.bat) for each network (e.g home, work etc) so they can execute them to quickly make the IP address, Gateway IP and DNS changes.

In order to successfully change the IP address via Command Prompt , Windows 7 requires the user to have administrative rights . This means even if you are not the administrator, you must know the administrative password , since you will be required to use the administrative command prompt .

Opening The Administrative Command Prompt On Windows 7

To open the administrative command prompt in Windows 7 , first click on the Start icon. In the search dialog box that appears, type cmd and right-click on the cmd search result displayed. On the menu that Windows brings up, click on the Run as administrator option as shown in the below screenshot:

Depending on your User Account Control Settings ( UAC ), Windows may ask for confirmation. If this happens, simply click on Yes and Windows will present the CLI prompt running in elevated administrator privileged mode :

Using The ‘netsh’ Command Prompt To Change The IP Address, Gateway IP & DNS

At the Administrative Command Prompt , type  netsh interface ip show config , which will display the network adapters available on your system and their names. Note down the name of the network adaptor for which you would like to set the static IP address.

In our example, we’ll be modifying the IP address of the interface named Wireless Network Connection , which is our laptop’s wireless network card.

Even if the Wireless Network Connection is set to be configured via DHCP , we can still configure a static IP address. Following is the command used to configure the interface with the IP address of 192.168.5.50 with a subnet mask of 255.255.255.0 and finally a Gateway of 192.168.5.1 :

Next, we configure our primary DNS server using the netsh command with the following parameters:

Note: When entering a DNS server, Windows will try to query the DNS server to validate it. If for any reason the DNS server is not reachable (therefore not validated), you might see the following error:

To configure the DNS server without requiring DNS Validation , use the validate=no parameter at the end of the command:

This command forces the DNS server setting without any validation and therefor no error will be presented at the CLI output in case the DNS server is not reachable.

To verify our new settings, use the netsh command with the following parameters:

At this point, we should see the network settings we configured, as shown below:

Using The 'netsh' Command Prompt To Set The Network Interface Card To DHCP

You can use the netsh command to switch your current adapter from static to DHCP.  To switch your network adaptor from static IP configuration to DHCP, use the following command:

Windows will not return any confirmation after the command is entered, however if the network adaptor has successfully obtained an IP address and has Internet connection, there should not be any network icon with an exclamation mark in the taskbar notification area as shown below:

Finally, to verify that DHCP is enabled and we’ve obtain an IP address, use the netsh command with the following parameters:

How do I change my IP Address on my computer? [duplicate]

My laptop is running Windows 7 and I connect my Wifi to my house. How do I change my computer's IP address without having to reset my internet router?

• superuser.com/a/312803/179299 –  Lorenzo Von Matterhorn Nov 23, 2013 at 21:58
• Why do you want to change it? What is the problem? –  Roland Smith Nov 23, 2013 at 22:05
• @RolandSmith This is for gaming reasons. Do you know how to change it though? –  puretppc Nov 23, 2013 at 22:08
• ipconfig /release and then ipconfig /renew in Command Prompt , but it depends on the Lease Time of your DHCP server in the router, you could get the same IP back. –  Alex Nov 23, 2013 at 22:11
• 2 @Tony Likely because that changed the router's WAN IP address. People outside your LAN cannot see into it. Changing your LAN IP addresses won't change anything visible from outside your LAN. (This is a classic XY problem . You asked how to do something you thought would solve your problem rather than telling us what your problem actually is and asking how to solve it.) –  David Schwartz Nov 23, 2013 at 22:46

Assuming you are using DHCP, your computer will be assigned an IP address from a pool of addresses. Generally, if you request a new address before the lease time is up, you will get the same address back.

So you will have to login to your router (most of them have a web interface, look at the manual) and change the IP that is assigned to your computer's. The most common way to do that is to assign your computer a specific IP address based on the MAC address of its network card.

The details of how to do this are specific to the router you have.

Most routers do network address translation ("NAT"), specifically one-to-many NAT. The machines on the internal network usually have 192.168.xxx.yyy addresses. But from the outside it looks like all the traffic is comming from one IP address (not in 192.168/16, because that range cannot be routed on the internet).

So it is not possible to directly expose your computer to the outside world (which in general is a good thing!).

But if you know which port (s) your gaming service/program uses, you might try to use port forwarding , so that every packet for the gaming port that arrives at the external interface of the router is sent to your PC. You can then point the other gamers to use the externally visible IP address on your router.

The only downside is that in this scenario it is difficult to have more than one gaming "server" on your internal network exposed to the internet. But virtual hosting combined with port forwarding could do the trick.

You should read the documentation that comes with your game thoroughly. Most home PC's are behind routers these days. So the games should know how to cope with that.

• Now that we know what his problem actually is , we know this won't solve it. –  David Schwartz Nov 23, 2013 at 22:48
• @DavidSchwartz: We (or at least I :-) still don't know exactly what the problem is. But I suspect it has something to do with using the laptop as a kind of server for a game, so having it reachable from the internet. So I added a piece about port forwarding. But I guess that the real answer to Tony's question can be found in the game's documentation, given that home routers a ubiquitous. –  Roland Smith Nov 24, 2013 at 0:08
• 1 Or he can look it up on Portforward.com . It has the biggest colection of routers with specific instruction how to forward ports for 100's of games on those routers (with images). –  Rik Nov 24, 2013 at 0:36
• @Rik That's probably the best answer to the question that wasn't asked but should have been. :-) –  Roland Smith Nov 24, 2013 at 10:53

Release and Renew Your IP Address in Microsoft Windows

Use the IPconfig command to fix common networking errors

• Massachusetts Institute of Technology
• University of Illinois

• Western Governors University
• The Ultimate Laptop Buying Guide

What to Know

• Release an IP address: Open Command Prompt , enter ipconfig /release , and press Enter .
• Renew an IP address: Open Command Prompt , enter ipconfig /renew , and press Enter .

Releasing and renewing the IP address on a computer with the Windows operating system resets the underlying IP connection, which often eliminates common IP-related issues, at least temporarily. It works in a few steps to disengage the network connection and refresh the IP address. Instructions apply to Windows 10, Windows 8.1, Windows 8, and Windows 7.

Windows: Release and Renew IP Addresses 

Under normal conditions, a device can use the same IP address indefinitely. Networks usually reassign correct addresses to devices when they first join. However, technical glitches with DHCP and network hardware can lead to IP conflicts and other problems that prevent the networking system from working correctly.

When to Release and Renew the IP Address

Scenarios in which releasing the IP address and then renewing it might be beneficial include:

• When connecting a computer to a modem.
• When physically moving a computer from one network to another, such as from an office network to home or home to a hotspot.
• When experiencing an unexpected network outage.

Release and Renew an IP Address With Command Prompt

Here's how to release and renew the address of any computer running the Windows operating system.

Open Command Prompt . The quickest method is to press Win + R to open the Run box dialog, enter cmd , and then press Enter .

Enter ipconfig /release and press Enter .

In the command results, the IP address line shows 0.0.0.0 as the IP address. This is normal because the command releases the IP address from the network adapter . During this time, your computer has no IP address and cannot access the internet.

Enter ipconfig /renew and press Enter to get a new address.

When the command is finished, a new line appears at the bottom of the Command Prompt screen that contains an IP address.

More Information About IP Release and Renew

Windows may receive the same IP address after renewal as it had before. This phenomenon is normal. The desired effect of deleting the old connection and starting a new one occurs independently of which address numbers are involved.

Attempts to renew the IP address may fail. One possible error message may read:

• An error occurred while renewing interface [interface name]: unable to contact your DHCP server. Request has timed out.

This error indicates that the DHCP server may be malfunctioning or is unreachable. Reboot the client device or the server before proceeding.

Windows also provide a troubleshooting section in Network and Sharing Center and Network Connections. These troubleshooting tools run diagnostics that include an equivalent IP renewal procedure if it detects that it's needed.

How to change your ip address from the command prompt in windows.

It's easy enough to change an IP address on your PC using Control Panel, but did you know you can also do it from the Command Prompt?

Quick Links

Launch command prompt as admin to use netsh, view your network information with command prompt, change your ip address, subnet mask, and default gateway, change your dns settings in command prompt, key takeaways.

• You must launch Command Prompt, PowerShell, or Terminal as admin to use netsh.
• Use the "netsh interface ipv4 show config" command to find the full name of the network interface you want to change.
• Modify your IP address, subnet mask, and default gateway using the command "netsh interface ipv4 set address". You can also change DNS settings using "netsh interface ipv4 set dns".

Changing your IP address with the Control Panel interface isn't difficult, but it does require clicking through a number of different windows and dialog boxes. If you're a fan of the Command Prompt, though, you can get it done more quickly using the netsh command, which is just one of the great network utilities built into Windows .

We're going to use the netsh command, but it requires that Command Prompt be launched as administrator to work. The netsh command allows you to configure just about any aspect of your network connections in Windows.

To launch Command Prompt (or PowerShell) as Admin, open up the Start Menu, search "cmd," hover over the result, then click "Run as Administrator."

In Windows 10 or Windows 11, you can also right-click the Start menu (or press Windows+X on your keyboard) to open the Power User Menu and choose "PowerShell (Admin)."

You can (and should ) use PowerShell for this instead.

Before you change your IP address and related information, you'll need to find the full name of the network for the interface you want to change. To do this, type the following command:

netsh interface ipv4 show config

Scroll down until you see the interface you're looking for. In our example, we're going to modify the Wi-Fi interface, which on our machine is just named "Wi-Fi." You'll also see other default names that Windows assigns to interfaces, such as "Local Area Connection," "Local Area Connection* 2," and "Ethernet." Just find the one you're looking for and make note of the exact name. You can also copy and paste the name to Notepad and then back into Command Prompt later to make things easier.

With the interface name in hand, you're ready to change the IP Address, subnet mask, and gateway. To do this, you'll issue a command using the following syntax:

netsh interface ipv4 set address name="YOUR INTERFACE NAME" static IP_ADDRESS SUBNET_MASK GATEWAY

So, for example, your command might look something like the following:

netsh interface ipv4 set address name="Wi-Fi" static 192.168.3.8 255.255.255.0 192.168.3.1

Where the info is replaced by whatever you want to use. In our example, the command does the following:

• Uses the interface name "Wi-Fi"
• Sets the IP address to 192.168.3.1
• Sets the subnet mask to 255.255.255.0
• Sets the default gateway to 192.168.3.1

And if you're using a static IP address but want to switch to using an IP address assigned automatically by a DHCP server — such as your router — you can use the following command instead:

netsh interface ipv4 set address name="YOUR INTERFACE NAME" source=dhcp

You can also use the netsh command to change the DNS servers used by a network interface. Third-party DNS servers — like Google Public DNS and OpenDNS —can be faster and more reliable than the DNS servers provided by your ISP. Whatever your reason for changing your DNS server , you can do it either at the router so it affects all the devices that get their information from the router or at the individual device. If you want to change the DNS servers for just one PC, it's easy to do with the netsh command.

You'll need to use the command twice: once to set your primary DNS server and once to set your secondary, or backup, DNS server. To set your primary DNS server, use the following syntax:

netsh interface ipv4 set dns name="YOUR INTERFACE NAME" static DNS_SERVER

So, for example, your command might look something like the following (in which we set it to Google's primary public DNS server, 8.8.8.8):

netsh interface ipv4 set dns name="Wi-Fi" static 8.8.8.8

To set your secondary DNS server, you'll use a very similar command:

netsh interface ipv4 set dns name="YOUR INTERFACE NAME" static DNS_SERVER index=2

So, continuing our example, you might set your secondary DNS as the Google Public DNS secondary server, which is 8.8.4.4:

netsh interface ipv4 set dns name="Wi-Fi" static 8.8.4.4 index=2

And just like with the IP address, you can also change it so that the network interface grabs its DNS settings automatically from a DHCP server instead. Just use the following command:

netsh interface ipv4 set dnsservers name"YOUR INTERFACE NAME" source=dhcp

And there you have it. Whether you like typing at the command prompt better or just want to impress your coworkers, now you know all the command line magic you need for changing your IP address settings.

Change TCP/IP settings

TCP/IP defines how your PC communicates with other PCs.

To make it easier to manage TCP/IP settings, we recommend using automated Dynamic Host Configuration Protocol (DHCP). DHCP automatically assigns Internet Protocol (IP) addresses to the computers on your network if your network supports it. If you use DHCP, then you don't have to change your TCP/IP settings if you move your PC to another location, and DHCP doesn't require you to manually configure TCP/IP settings, such as Domain Name System (DNS) and Windows Internet Name Service (WINS).

To enable DHCP or change other TCP/IP settings

Select  Start , then type settings . Select  Settings  >  Network & internet .

Do one of the following:

For a Wi-Fi network, select  Wi-Fi  >  Manage known networks . Choose the network for which you want to change the settings.

For an Ethernet network, select  Ethernet , then select the Ethernet network you’re connected to.

Next to  IP assignment , select  Edit .

Under  Edit network IP settings or Edit IP settings , select  Automatic (DHCP)  or  Manual .

To specify IPv4 settings manually

Under  Edit network IP settings or Edit IP settings , choose  Manual , then turn on  IPv4 .

To specify an IP address, in the  IP address, Subnet mask , and  Gateway  boxes, type the IP address settings.

To specify a DNS server address, in the  Preferred DNS  and  Alternate DNS  boxes, type the addresses of the primary and secondary DNS servers.

To specify if you want to use an encrypted (DNS over HTTPS) or unencrypted connection to the DNS server or servers you specify, for DNS over HTTPS , choose the setting you want:

Off : All DNS queries will be sent to the DNS server unencrypted in plaintext over HTTP.

On (automatic template) : DNS queries will be encrypted and sent to the DNS server over HTTPS. DNS queries will use the default settings for the automatic template or try to discover them automatically.

On (manual template) : DNS queries will be encrypted and sent to the DNS server over HTTPS. They’ll use the settings you enter in the DNS over HTTPS template box.

If you use DNS over HTTPS (automatic or manual template), turn Fallback to plaintext on or off:

When it’s turned on, a DNS query will be sent unencrypted if it can’t be sent over HTTPS.

When it’s turned off, a DNS query won’t be sent if it can’t be sent over HTTPS.

To specify IPv6 settings manually

Under  Edit network IP settings or Edit IP settings , choose  Manual , then turn on  IPv6 .

To specify an IP address, in the  IP address , Subnet prefix length , and  Gateway  boxes, type the IP address settings.

When you select  Automatic (DHCP) , the IP address settings and DNS server address setting are set automatically by your router or other access point (recommended).

When you select  Manual , you can manually set your IP address settings and DNS server address.

When you’re done, select  Save .

Note:  To install IPv4, run Command Prompt as an administrator, type netsh interface ipv4 install , and then press Enter .

Select Start   , then select Settings   > Network & Internet   .

For a Wi-Fi network, select Wi-Fi   > Manage known networks . Choose the network you want to change the settings for, then select Properties.

For an Ethernet network, select Ethernet , then select the Ethernet network you’re connected to.

Under IP assignment , select Edit .

Under Edit IP settings , select Automatic (DHCP) or Manual .

Under Edit IP settings , choose Manual , then turn on IPv4 .

To specify an IP address, in the IP address, Subnet prefix length , and Gateway boxes, type the IP address settings.

To specify a DNS server address, in the Preferred DNS and Alternate DNS boxes, type the addresses of the primary and secondary DNS servers.

Under Edit IP settings , choose Manual , then turn on IPv6 .

When you select Automatic (DHCP) , the IP address settings and DNS server address setting are set automatically by your router or other access point (recommended).

When you select Manual , you can manually set your IP address settings and DNS server address.

When you’re done, select Save .

In Windows 8.1, select the Start button, start typing View network connections , and then select View network connections in the list.

In Windows 7, open Network Connections by selecting the Start button, and then selecting Control Panel . In the search box, type adapter , and then, under Network and Sharing Center , select View network connections .

Right-click the connection that you want to change, and then select Properties . If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

Select the Networking tab. Under This connection uses the following items , select either Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) , and then select Properties .

To specify IPv4 IP address settings, do one of the following:

To get IP settings automatically using DHCP, select Obtain an IP address automatically , and then select OK .

To specify an IP address, select Use the following IP address , and then, in the IP address, Subnet mask , and Default gateway boxes, type the IP address settings.

To specify IPv6 IP address settings, do one of the following:

To get IP settings automatically using DHCP, select Obtain an IPv6 address automatically , and then select OK .

To specify an IP address, select Use the following IPv6 address , and then, in the IPv6 address, Subnet prefix length , and Default gateway boxes, type the IP address settings.

How to change the IP address of a network adapter

• 3 contributors

This article provides some information about how to change the IP address of a network adapter.

Applies to:   Windows Server 2012 R2 Original KB number:   323444

This article describes how to change the Internet Protocol (IP) address that is assigned to a network adapter. An IP address may be assigned automatically if your network has a Dynamic Host Configuration Protocol (DHCP) server, or you can specify an IP address.

How to change the IP address assigned to a Network Adapter

• Log on to the computer by using the Administrator account.
• Click Start, point to Control Panel, and click Network Connections.
• Right-click the local area connection that you want to modify and then click Properties .
• In the This connection uses the following items box, click Internet Protocol (TCP/IP), and then click Properties. The Internet Protocol (TCP/IP) Properties dialog box appears.
• Continue with the steps in one of the following two sections, depending on your circumstances.

How to automatically obtain an IP Address

Follow these steps to configure the computer to obtain an IP address from a DHCP server. You must have a DHCP server.

Click Obtain an IP address automatically .

Click Obtain DNS server address automatically if you do not want to specify the IP address of the Domain Name System (DNS) server.

• Click OK. In the Local Area Connection Properties dialog box, click Close.
• In the Local Area Connection Status dialog box, click Close.

Click Start, and then click Run.

In the Open box, type cmd, and then click OK.

At the command prompt, type ipconfig /release, and then press ENTER.

Type ipconfig /renew, and then press ENTER.

The network adapter is assigned an IP address by the DHCP server, and a message similar to the following appears:

Type exit, and then press ENTER to quit the command prompt.

How to Specify an IP Address

To assign an IP address to the network adapter, follow these steps:

• Click Use the following IP address if you want to specify the IP address for the network adapter.
• In the IP address box, type the IP address that you want to assign to this network adapter. This IP address must be a unique address in the range of addresses that are available for your network. Contact the network administrator to obtain a list of valid IP addresses for your network.
• In the Subnet mask box, type the subnet mask for your network.
• In the Default gateway box, type the IP address of the computer or device on your network that connects your network to another network or to the Internet.
• In the Preferred DNS server box, type the IP address of the computer that resolves host names to IP addresses.
• In the Alternate DNS server box, type the IP address of the DNS computer that you want to use if the preferred DNS server becomes unavailable.

Troubleshooting

There is an IP address conflict: If you try to assign an IP address that is already in use, you receive the following error message:

The static IP address that was just configured is already in use on the network. Please reconfigure a different IP address.

In this case, assign an unused IP address to the network adapter.

Your computer cannot connect to other computers on the network: If you assign an incorrect subnet mask address to the network adapter, the computer is effectively located on a different network. You cannot connect to other computers on the network.

Your computer cannot connect to other computers by using host names: If you assign an incorrect DNS server IP address, or if you do not use a DNS server, you cannot connect to computers by using their host names. It prevents you from browsing the Internet. You can connect to other computers by using their IP addresses.

To work around this issue in a local network, add host-name-to-IP-address mappings in a Hosts file.

Change the hostname of your AL2 instance

When you launch an instance into a private VPC, Amazon EC2 assigns a guest OS hostname. The type of hostname that Amazon EC2 assigns depends on your subnet settings. For more information about EC2 hostnames, see Amazon EC2 instance hostname types in the Amazon EC2 User Guide for Linux Instances .

A typical Amazon EC2 private DNS name for an EC2 instance configured to use IP-based naming with an IPv4 address looks something like this: ip-12-34-56-78.us-west-2.compute.internal , where the name consists of the internal domain, the service (in this case, compute ), the region, and a form of the private IPv4 address. Part of this hostname is displayed at the shell prompt when you log into your instance (for example, ip-12-34-56-78 ). Each time you stop and restart your Amazon EC2 instance (unless you are using an Elastic IP address), the public IPv4 address changes, and so does your public DNS name, system hostname, and shell prompt.

This information applies to Amazon Linux. For information about other distributions, see their specific documentation.

Change the system hostname

If you have a public DNS name registered for the IP address of your instance (such as webserver.mydomain.com ), you can set the system hostname so your instance identifies itself as a part of that domain. This also changes the shell prompt so that it displays the first portion of this name instead of the hostname supplied by AWS (for example, ip-12-34-56-78 ). If you do not have a public DNS name registered, you can still change the hostname, but the process is a little different.

In order for your hostname update to persist, you must verify that the preserve_hostname cloud-init setting is set to true . You can run the following command to edit or add this setting:

If the preserve_hostname setting is not listed, add the following line of text to the end of the file:

To change the system hostname to a public DNS name

Follow this procedure if you already have a public DNS name registered.

For AL2: Use the hostnamectl command to set your hostname to reflect the fully qualified domain name (such as webserver.mydomain.com ).

For Amazon Linux AMI: On your instance, open the /etc/sysconfig/network configuration file in your favorite text editor and change the HOSTNAME entry to reflect the fully qualified domain name (such as webserver.mydomain.com ).

Reboot the instance to pick up the new hostname.

Alternatively, you can reboot using the Amazon EC2 console (on the Instances page, select the instance and choose Instance state , Reboot instance ).

Log into your instance and verify that the hostname has been updated. Your prompt should show the new hostname (up to the first ".") and the hostname command should show the fully-qualified domain name.

To change the system hostname without a public DNS name

For AL2: Use the hostnamectl command to set your hostname to reflect the desired system hostname (such as webserver ).

For Amazon Linux AMI: On your instance, open the /etc/sysconfig/network configuration file in your favorite text editor and change the HOSTNAME entry to reflect the desired system hostname (such as webserver ).

Open the /etc/hosts file in your favorite text editor and change the entry beginning with 127.0.0.1 to match the example below, substituting your own hostname.

You can also implement more programmatic solutions, such as specifying user data to configure your instance. If your instance is part of an Auto Scaling group, you can use lifecycle hooks to define user data. For more information, see Run commands on your Linux instance at launch and Lifecycle hook for instance launch in the AWS CloudFormation User Guide .

Change the shell prompt without affecting the hostname

If you do not want to modify the hostname for your instance, but you would like to have a more useful system name (such as webserver ) displayed than the private name supplied by AWS (for example, ip-12-34-56-78 ), you can edit the shell prompt configuration files to display your system nickname instead of the hostname.

To change the shell prompt to a host nickname

Create a file in /etc/profile.d that sets the environment variable called NICKNAME to the value you want in the shell prompt. For example, to set the system nickname to webserver , run the following command.

Open the /etc/bashrc (Red Hat) or /etc/bash.bashrc (Debian/Ubuntu) file in your favorite text editor (such as vim or nano ). You need to use sudo with the editor command because /etc/bashrc and /etc/bash.bashrc are owned by root .

Edit the file and change the shell prompt variable ( PS1 ) to display your nickname instead of the hostname. Find the following line that sets the shell prompt in /etc/bashrc or /etc/bash.bashrc (several surrounding lines are shown below for context; look for the line that starts with [ "$PS1" ):

Change the \h (the symbol for hostname ) in that line to the value of the NICKNAME variable.

(Optional) To set the title on shell windows to the new nickname, complete the following steps.

Create a file named /etc/sysconfig/bash-prompt-xterm .

Make the file executable using the following command.

Open the /etc/sysconfig/bash-prompt-xterm file in your favorite text editor (such as vim or nano ). You need to use sudo with the editor command because /etc/sysconfig/bash-prompt-xterm is owned by root .

Add the following line to the file.

Log out and then log back in to pick up the new nickname value.

Change the hostname on other Linux distributions

The procedures on this page are intended for use with Amazon Linux only. For more information about other Linux distributions, see their specific documentation and the following articles:
