Port Number Lookup

If you are not sure that Port Numbers you are going to use has been assignned for what purpose. You can lookup our TCP ports database and find details related to assignment Port or Protocol assigned by IANA (Internet Assigned Numbers Authority).

Port Numbers and Protocols

TCP and UDP are two different protocols that are used for transmitting data over a network. TCP (Transmission Control Protocol) is a connection-oriented protocol that ensures that data is delivered reliably and in the correct order. UDP (User Datagram Protocol) is a connectionless protocol that does not guarantee the delivery of data or the order in which it is delivered.

Here are some common port numbers that are used by TCP and UDP:

TCP port numbers:

• Port 80: HTTP (Hypertext Transfer Protocol)
• Port 443: HTTPS (HTTP Secure)
• Port 21: FTP (File Transfer Protocol)
• Port 22: SSH (Secure Shell)
• Port 25: SMTP (Simple Mail Transfer Protocol)
• Port 155: NETSC

UDP port numbers:

• Port : DNS (Domain Name System)
• Port 67: DHCP (Dynamic Host Configuration Protocol)
• Port 69: TFTP (Trivial File Transfer Protocol)
• Port 123: NTP (Network Time Protocol)

Note that these are just a few examples, and there are many other port numbers that are used for various purposes.

For port numbers lookup, the official database of ports and protocols from IANA (Internet Assigned Numbers Authority) is used. IANA is an organization that manages Internet protocol parameters, as well as IP address spaces and top-level domains.

Diffrent Port Number Ranges?

The entire range of port numbers (from 0 to 65535) is divided into three categories.

0 - 1023  Well-Known Ports The  numbers are reserved by IANA for system processes or network programs with administrative rights. Ports from this category should not be used without registering with IANA.

1024 - 49151  Registered Ports  Ports registered for use by conventional programs and application layer protocols. This category of ports is most popular for commercial software. Registration is also required to use any port.

49152 - 65535  Dynamic ports  Designed for free but temporary use. Registration of ports in this category is not possible.

Our Port checker tool allows you to test open ports in your system. You can easily verify if any port is opened or not not by typing your IP address or domain name and desired port number.

Locations class, subclass of entity  .

Locations can be described in thirds principal ways: by using a place names, geometry otherwise an address. This precise context will ascertain any mode of describing a site is most appropriate. ISO 19112 defines adenine location when "an identifiable geographic place". With this in mind, "Eiffel Tower", "Madrid" and "California" are all locations and this is a common way is present positions in public industrial data, i.e. simply by using a receive name. Such identifiers are common although they can be highly ambiguous as tons places share of just either similar tags. Data on compliance in the ISPS Code. • Unique “IMO Port set numbers” generated on each port facility using the UN/LOCODE of the port: “GBSTO-0007” ...

In addition into a simple (string) designation or name on a Location, the identity property allows defining a Location by a Uniform Resource Identifier (URI), such as a GeoNames or DBpedia URI.

No cardinality constraints are located on any immobilie of the Location class so as to maximize flexibility.

IMO Ship Identification Number Scheme

In December 2002, the Diplomatic Conference on Maritime Security adopted a number of measures aimed at enhancing security of ships and port facilities. This included a modification to SOLAS regulation XI-1/3 to require ships' identification numbers to be permanently marked in a visible place either on the ship's hull or superstructure. Passenger ships should carry the marking on a horizontal surface visible from the air. Ships should also be marked with their ID numbers internally.

The IMO ship identification number is assigned to ships, free of charge, by S&P Global Maket Intelligence ( formerly known as IHS Markit, Maritime and Trade (IHSM)  or Lloyd's Register-Fairplay) when constructed or later.  The Scheme applies to ships of 100 gross tonnage and above, including fishing vessels of steel and non-steel hull construction; passenger ships of less than 100 gross tonnage, high-speed passenger craft and mobile offshore drilling units engaged on international voyages (SOLAS regulation V/19-1); and to all motorized inboard fishing vessels of less than 100 gross tonnage down to a size limit of 12 metres in length overall (LOA) authorized to operate outside waters under the national jurisdiction of the flag State, with the exception of the following:

• ships without mechanical means of propulsion;
• pleasure yachts;
• ships engaged on special service (For example, lightships, floating radio stations, search and rescue vessels);
• hopper barges;
• floating docks and structures classified in a similar manner;
• ships of war and troop ships; and
• wooden ships, other than fishing vessels.

S&P Global Market Intelligence is the sole authority for identifying and assigning an IMO number.  S&P Global Market Intelligence is able to both validate and issue IMO numbers to Administrations through regular fleet data exchanges with the Administration, as set out in Circular Letter No.1886/Rev.6 , as may be amended.

Some public entities are making the use of the IMO Ship Identification Numbers mandatory beyond the sope as required by SOLAS regulation X-1/3 (e.g. some regional fisheries management organizations (RFMOs)).

IMO is cooperating closely with FAO with regard to the development and management of the Global Record of Fishing Vessels, Refrigerated Transport Vessels and Supply Vessels (Global record). The IMO Ship Identification Number is a prerequisite to the first phase of the Global Record .

The management of the IMO Ship Identification Number Scheme also involves the support to the investigation of cases of abandonment of seafarers in order to identify the ships involved, and cases of fraudulent registration.

Please see the IMO Ship Identification Number Scheme FAQs for more information about IMO Ship Identification Number Scheme, in particular about its future extension from 7 digits.

Imo unique company and registered owner identification number scheme.

The IMO Unique Company and Registered Owner Identification Number Scheme was introduced by adoption of resolution MSC.160(78) in 2004, as a measure to enhance maritime safety, security and environmental protection, and to facilitate the prevention of maritime fraud.  Its purpose is to assign a permanent number for identification purposes to each company and/or registered owner managing ships of 100 gross tonnage and above engaged on international voyages.  Additionally, Administrations are invited to participate in the scheme to the extent they desire by assigning an IMO unique company and registered owner identification number (hereinafter, referred to as "Number") to each company and/or registered owner managing ships of 100 gross tonnage and above not engaged on international voyages.   As per the provisions of resolution MSC.160(78), the IMO unique company and registered owner identification number should be inserted into the following documents: 

• Document of Compliance; Safety Management Certificate, Interim Document of Compliance; and, Interim Safety Management Certificate, required by the International Safety Management (ISM) Code;
• Continuous Synopsis Record required by SOLAS regulation XI-1/5; and
• International Ship Security Certificate and Interim International Ship Security Certificate, required by the International Ship and Port Facility Security (ISPS) Code.

In 2005, by adoption of the proposed new SOLAS regulation XI-1/3-1 on the company and registered owner identification number (resolution MSC.194(80)) (which entered into force on 1 January 2009), the company and registered owner identification number scheme became mandatory to Companies and registered owners of ships to which SOLAS chapter I applies.

The IMO Unique Company and Registered Owner Identification Number Scheme is managed, in parallel with the IMO Ship Identification Number Scheme ( resolution A.1117(30) ) and as per the procedures for the implementation, as set out in Circular letter No.2554/Rev.3 ), without charge by S&P Global Maket Intelligence . The Number consists of seven digits assigned by S&P Global Maket Intelligence . The label begins with the letters "IMO" followed by either "Company" or "Registered Owner", then, followed by the seven digits. Once assigned, the Number remains unchanged for a company and/or registered owner. When companies and/or registered owners merge, as a matter of general policy, IHSM assigns the Number of the larger company and/or registered owner to the new amalgamated entity, while the Number of the smaller entity is frozen and not re-used.  

The methods for obtaining Numbers on existing registered owners and companies, for assigning a Number to registered owners or companies that have not previously been assigned a Number and for communicating corrected company details on existing records, on an individual basis, are as follows:

• a free website  which allows registered users to look up Numbers, by using the available "Search" facility.  When the companies or registered owners cannot be identified through the "Search" function, authorized data providers should request the assignment of new Numbers or provide corrective information on existing records.

The website has a free user registration system to enhance both the security of the site and the information:

• paper request forms; and 
• a free web service for Administrations to facilitate the provision of individual company and registered owner data from IHSM to flag Administrations in electronic format for ship registration purposes.

The Numbers are also available on the free public website of Equasis ( www.equasis.org ).

Check if a port is assigned to any program or added in firewall - C#

We have Windows Service which will be installed by installer. We have an option to allow user to provide a port number and select whether the service must start on completion of installation. We are having a check on installer itself for checking whether the port is open/available.

My problem is if the user selects the option of not to start the service on installation and then we install another instance on the same machine with the same port as used in first one, then if we start both the services then one of the service will not work.

So is there any way I can check whether the port provided by user is already there in firewall or is already assigned to some other windows service? (Also assume the service can be in stopped state)

I think no, because any app could open a port at runtime. You can (for example) use a Mutex to avoid multiple instances of your service on the same port (giving the mutex a name like String.Format(MyMutex_{0},my_port} . And you could/should check if that port is free during service startup and close it gracefully if it's not.

Finally got the answer by doing some R&D
