How to set a static ip address in ubuntu.

When static is the way forward.

Quick Links

What is a static ip address, setting a static ip in ubuntu, set a static ip in ubuntu with the gui, connection convenience, key takeaways.

After gathering your connection name, subnet mask, and default gateway, you can set a static IP address in the terminal using the nmcli command. Or, in the GNOME desktop, open your connection settings and click the + icon, then enter the info for your static IP address there.

Your home network relies on IP addresses to route data between devices, and sometimes on reconnecting to the network a device's address can change. Here's how to give an Ubuntu Linux computer a permanent IP address that survives reboots.

Everything on your network home network, whether it's using a wired connection or Wi-Fi, has an IP address . IP stands for Internet Protocol. An IP address is a sequence of four numbers separated by three dots. Each IP address that is unique within that network.

IP addresses act as numeric labels. Your router uses these labels to send data between the correct devices. Usually, your router assigns IP addresses. It knows which IP addresses are in use and which are free. When a new device connects to the network, it requests an IP address and the router allocates one of the unused IP addresses. This is called DHCP, or dynamic host configuration protocol .

When a device is restarted or powered off and on, it may receive its old IP address once more, or it might be allocated a new IP address. This is normal for DHCP and it doesn't affect the normal running of your network. But if you have a server or some other computer that you need to be able to reach by its IP address, you'll run into problems if its IP address doesn't survive power downs or reboots.

Pinning a specific IP address to a computer is called allocating a static IP address . A static IP address, as its name suggests, isn't dynamic and it doesn't change even if the computer is power-cycled .

Nmcli is the command-line network manager tool , and can be used to change your IP address, configure network devices, and --- relevant to our purposes --- set up a static IP in Ubuntu.

We're demonstrating this technique on Ubuntu 22.04 LTS, but it ought to work on any Linux distribution, including Ubuntu 23.04. The nmcli tool was released in 2004, so it should be present on just about any standard distribution.

Let's take a look at the network connections that already exist on the computer. We're using the connection command with the show argument.

nmcli connection show

This displays some information about each connection. We only have a single connection configured.

The output is wider than the terminal window. This is the information that we're shown.

  • Name : Our network connection is called "netplan-enp0s3."
  • UUID : The universally unique identifier Linux uses to reference this connection internally.
  • Type : This is an ethernet connection.
  • Device : This connection is using the "enp0s3" network interface. It's the only network card in this computer.

We can use the ip command to discover the IP address this computer is using.

In the output we can see the "enp0s3" entry, and its current IP address, 192.168.86.117. The "/24" is a shorthand way of saying that this network uses a 255.255.255.0 subnet mask . Take a note of this number, we'll need to use it later.

We need to choose the IP address we're going to set as our static IP address. Obviously, you can't use an IP address that is already in use by another device. One safe way to proceed is to use the current IP address assigned to the Ubuntu system. We know for certain that nothing else is using that IP address.

If we want to use a different IP address, try pinging it. We're going to test whether IP address 192.168.86.128 is in use. If everything else on your network uses DHCP and you get no response to the ping command, it should be safe to use.

ping 192.168.86.128

Even if another device had previously used that IP address, it'll be given a new IP address when it next boots up. Nothing responds to the ping requests, so we're clear to go ahead and configure 192.168.86.128 as our new static IP.

We also need to know the IP address of your default gateway , which will usually be your broadband router. We can find this using the ip command and the route option, which we can abbreviate to "r."

The entry that starts with "default" is the route to the default gateway. Its IP address is 192.168.86.1. Now we can start to issue commands to set up our static IP address.

The first command is a long one.

sudo nmcli con add con-name "static-ip" ifname enp0s3 type ethernet ip4 192.168.86.128/24 gw4 192.168.86.1

Taken in small chunks, it's not as bad as it looks. We're using sudo . The nmcli arguments are:

  • con : Short for "connection."
  • add : We're going to add a connection.
  • con-name "static-ip" : The name of our new connection will be "static-ip."
  • ifname enp0s3 : The connection will use network interface "enp0s3."
  • type ethernet : We're creating an ethernet connection.
  • ip4 192.168.86.128/24 : The IP address and subnet mask in classless inter-domain routing notation . This is where you need to use the number you took note of earlier.
  • gw4 192.168.86.1 : The IP address of the gateway we want this connection to use.

To make our connection a functioning connection, we need to provide a few more details. Our connection exists now, so we're not adding anything, we're modifying settings, so we use the mod argument. The setting we're changing is the IPv4 DNS settings. 8.8.8.8 is the IP address of Google's primary public DNS server , and 8.8.4.4 is Google's fallback DNS server.

Note that there is a "v" in "ipv4." In the previous command the syntax was "ip4" without a "v." The "v" needs to be used when you're modifying settings, but not when adding connections.

nmcli con mod "static-ip" ipv4.dns "8.8.8.8,8.8.4.4"

To make our IP address static, we need to change the method which the IP address obtains its value. The default is "auto" which is the setting for DHCP. We need to set it to "manual."

nmcli con mod "static-ip" ipv4.method manual

And now we can start or "bring up" our new connection.

nmcli con up "static-ip" ifname enp0s3

We didn't get any error messages which is great. Lets use nmcli to look at our connections once more.

nmcli con show

Here's the output:

Our static-ip connection is active and using device "enp0s3." The existing connection "netplan-enp0s3" is no longer associated with a physical network interface because we've pinched "enp0s3" from it.

Click the icons at the far-right end of the system bar to show the system menu, then click on the "Wired Connected" menu option. If you're using a wireless connection, instead click the name of your Wi-Fi network.

The available connections are displayed. A dot indicates which is in use. Click the "Wired Settings" or "Wi-Fi Settings" menu option. The details of the active connection are displayed.

If you followed our previous instructions the new connection will be the active connection. We can see our new "static-ip" connection has the IP address, default gateway, and DNS servers that we set for it.

To create a new connection using the "Settings" application, click the " + " icon on the "Networks" page, above the list of wired connections.

A dialog appears. We need to provide a name for our new static IP connection.

We're calling our new connection "static-2." Click the "IPv4" tab.

Select the "Manual" radio button, and complete the "Address", "Netmask", and "Gateway" fields. Also complete the DNS field, and then click the green "Apply" button. Note the comma between the DNS entries.

Our new connection is listed in the "Wired" connections pane.

You can swap between the available connections by clicking directly on their names.

If you want to modify a connection after you create it, click the cog icon. In this case, we'll enter the settings for the "static-ip" connection.

A dialog box opens. Click on the "IPv4" tab.

Because we set our new IP address to be static, the "Manual" radio button is selected. You could change this back to DHCP by selecting the "Automatic (DHCP)" radio button, and clicking the green "Apply" button.

Using the nmcli command or the GNOME desktop and apps, you can hop between network connections very easily and very quickly.

It's more convenient to have a selection of connection profiles and move between them as you need to, rather than to have one that you keep editing. If something goes horribly wrong with the connection you're editing or adding, you can always fall back on one of the existing connections.

How to Assign Static IP Address on Ubuntu Linux

Dimitrios

Brief: In this tutorial, you’ll learn how to assign static IP address on Ubuntu and other Linux distributions. Both command line and GUI methods have been discussed.

IP addresses on Linux Systems in most cases are assigned by Dynamic Host Configuration Protocol (DHCP) servers. IP addresses assigned this way are dynamic which means that the IP address might change when you restart your Ubuntu system . It’s not necessary but it may happen.

Dynamic IP is not an issue for normal desktop Linux users in most cases . It could become an issue if you have employed some special kind of networking between your computers.

For example, you can share your keyboard and mouse between Ubuntu and Raspberry Pi . The configuration uses IP addresses of both system. If the IP address changes dynamically, then your setup won’t work.

Another use case is with servers or remotely administered desktops. It is easier to set static addresses on those systems for connection stability and consistency between the users and applications.

In this tutorial, I’ll show you how to set up static IP address on Ubuntu based Linux distributions. Let me show you the command line way first and then I’ll show the graphical way of doing it on desktop.

Method 1: Assign static IP in Ubuntu using command line

Static IP set up Ubuntu

Note for desktop users : Use static IP only when you need it. Automatic IP saves you a lot of headache in handling network configuration.

Step 1: Get the name of network interface and the default gateway

The first thing you need to know is the name of the network interface for which you have to set up the static IP.

You can either use ip command or the network manager CLI like this:

In my case, it shows my Ethernet (wired) network is called enp0s25:

Next, you should note the default gateway IP using the Linux command ip route :

As you can guess, the default gateway is 192.168.31.1 for me.

Step 2: Locate Netplan configuration

Ubuntu 18.04 LTS and later versions use Netplan for managing the network configuration. Netplan configuration are driven by .yaml files located in /etc/netplan directory.

By default, you should see a .yaml file named something like 01-network-manager-all.yaml, 50-cloud-init.yaml, 01-netcfg.yaml.

Whatever maybe the name, its content should look like this:

You need to edit this file for using static IP.

Step 3: Edit Netplan configuration for assigning static IP

Just for the sake of it, make a backup of your yaml file.

Please make sure to use the correct yaml file name in the commands from here onward.

Use nano editor with sudo to open the yaml file like this:

Please note that yaml files use spaces for indentation . If you use tab or incorrect indention, your changes won’t be saved.

You should edit the file and make it look like this by providing the actual details of your IP address, gateway, interface name etc.

In the above file, I have set the static IP to 192.168.31.16.

Save the file and apply the changes with this command:

You can verify it by displaying your ip address in the terminal with ‘ip a’ command.

If you don’t want to use the static IP address anymore, you can revert easily.

If you have backed up the original yaml file, you can delete the new one and use the backup one.

Otherwise, you can change the yaml file again and make it look like this:

Method 2: Switch to static IP address in Ubuntu graphically

If you are on desktop, using the graphical method is easier and faster.

Go to the settings and look for network settings. Click the gear symbol adjacent to your network connection.

Assign Static IP address in Ubuntu Linux

Next, you should go to the IPv4 tab. Under the IPv4 Method section, click on Manual.

In the Addresses section, enter the IP static IP address you want, netmask is usually 24 and you already know your gateway IP with the ip route command.

You may also change the DNS server if you want. You can keep Routes section to Automatic.

Assigning static IP in Ubuntu Linux

Once everything is done, click on Apply button. See, how easy it is to set a static IP address graphically.

How to Configure Static IP Address on Ubuntu 22.04 LTS and 22.10

Switching from dynamic IP allocation to static IP addresses is easy on Ubuntu 22.04 "Jammy Jellyfish" and 22.10.

The IP addresses of most devices today are generated by Dynamic Host Configuration Protocol (DHCP) servers. A DHCP server assigns a dynamic IP address to your device when it's connected to a network. Thus, you have the chance to change this IP address from time to time.

On the other hand, a static IP refers to a fixed, immutable address, different from dynamic IPs. You can set static IP settings for Ubuntu 22.04 LTS and 22.10 in three different ways. Here's how to get started.

Understanding IP Configuration in Ubuntu

Ubuntu's progression in network management has made configuring settings like the static IP more user-friendly. The feature to set a static IP in Ubuntu 22.04, in particular, has advantages in terms of network efficiency and stability.

Unlike dynamic IPs, which might vary over sessions, a static IP in Ubuntu remains consistent. This is especially advantageous for servers where consistent address recognition is paramount. For these servers, static IP configurations can become a necessity.

While the graphical interface offers a more intuitive way to handle IP configurations, using the static IP command line can offer more precision. For users who want granular control over their network configurations, command-line methods are a preferred choice. By mastering this method, users can ensure optimal Ubuntu IP configuration for their needs.

However, the benefits of a static IP in Ubuntu, especially in the 22.04 version, come with responsibilities. Ensuring that these IPs are correctly set up is crucial, as misconfigurations can lead to network vulnerabilities.

So follow the steps below to configure a static IP address on your Ubuntu machine correctly.

Set a Static IP on Ubuntu With the nmcli Command

It's pretty easy to configure Ubuntu 22.04 static IP settings using the nmcli command . nmcli is a text-based utility used to check the status of the wired connections you are using on your device.

With this command, you can access additional networking information such as your connection status, the name of your host device, and general permissions in your network configuration. If you're aiming to set a static IP on an Ubuntu server, this command proves invaluable.

You can get information about your connection with:

The output of this command will be as follows:

Create a static link with the command given below. Then, manually configure the enp0s3 and ipv4 settings with the appropriate parameters in the nmcli command:

If you use the nmcli connection show command again, you can see that the static link has been added.

After this process, add the static connection you created to the DNS IP:

Now use the command below to activate the connection:

If the output displays "connection successfully activated," you've successfully set up a static IP address on your machine.

You can consider using static IP addresses to avoid connection problems caused by dynamic IP addresses. A static IP address allows you to have a fixed identity and location when connected to the internet.

You can verify the static IP you want to assign to your device by running:

Using netplan for Static IP Settings on Ubuntu

Just like nmcli, another command you can use for setting a static IP on Ubuntu is netplan. You can easily make Ubuntu static IP settings using the netplan command in 22.04 LTS and 22.10 versions. To do this, follow the steps below.

First, find out the name of your network interface using:

What you see here is your network interface name. This name may be different on each device.

Now, create a file named 01-netcfg.yaml in the /etc/netplan folder. Edit it with your favorite text editor.

Add the following lines to the file:

As you can see, you have disabled the DHCP IP setting with the dhcp4: no statement. You've then added the IP address and DNS settings assigned by Google.

After saving this file, run the following to apply the changes:

Configure Static IP Settings on Ubuntu Graphically

The graphical network interface in Ubuntu 22.04 is quite useful if you don't want to use the command line. So much so that you can easily set the Ubuntu static IP address using this interface.

To do this, click on the Network icon in the upper right corner of your desktop. Then, select Wired Settings from the drop-down menu. Click on the Gear icon to open the settings window.

Then, switch to the IPv4 tab in the window that opens.

As you can see, DHCP is enabled by default. Change the IPv4 Method to Manual as you want to use a static IP instead of a dynamic one. Next, change your address, netmask, and gateway settings. Finally, modify your DNS setting and click the Apply button.

You must restart this wired connection for all these actions to take effect. To do this, simply toggle the switch next to the network name on and then off.

Why Should You Use Static IP Addresses on Ubuntu?

You've now understood how to configure a static IP in Ubuntu, especially in the "Jammy Jellyfish" 22.04 LTS version and 22.10, using both graphical and command-line methods with nmcli and netplan.

Due to insufficient IP addresses, some service providers may assign the same address to two different users. In this case, connection problems can occur. Using static IP addresses instead does not cause such problems as it is user-specific, but beware as someone can misuse your IP address in several ways.
