On this page you can find tools for search TCP Port Numbers and UDP Port Numbers.
Current service contain the biggest tcp udp port list. Port search going through 4 library (database),
total number of records are about 22000 (in 3 times more that in other service).
Library's:
  • IANA port numbers assignments library (database) - The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.
  • WIKI port numbers assignments library (database) - Good known wikipedia ports library
  • Gasmy library, Beta Library - good known manualy created port databases.
In computer networking, the protocols of the Transport Layer of the Internet Protocol Suite, most notably the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP),
use a numerical identifier for the data structures of the endpoints for host-to-host communications.
Such an endpoint is known as a port and the identifier is the port number.
The Registered Ports are listed by the IANA and on most systems can be used by ordinary user processes or programs executed by ordinary users. Thats why most part of new programs that useing "sockets" bind to ports in this range. Ports are used in the TCP [RFC793] to name the ends of logical connections which carry long term conversations. For the purpose of providing services to unknown callers, a service contact port is defined.
The IANA registers uses of these ports as a convenience to the community. About half part of numbers from range are free at this moment. To the extent possible, these same situation with for UDP ports [RFC768]. The Registered Ports are in the range 1024-49151.
It's very easy to search, just input tcp ports range or udp ports range - example2 (or in list format - example1),and 'Go'.

The User Datagram Protocol (UDP) is one of the core members of the Internet Protocol Suite, the set of network protocols used for the Internet. With UDP, computer applications can send messages, sometimes known as datagrams, to other hosts on an Internet Protocol (IP) network without requiring prior communications to set up special transmission channels or data paths. UDP is sometimes called the Universal Datagram Protocol. The protocol was designed by David P. Reed in 1980 and formally defined in RFC 768.

In computer networking, the protocols of the Transport Layer of the Internet Protocol Suite, most notably the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), but also other protocols, use a numerical identifier for the data structures of the endpoints for host-to-host communications. Such an endpoint is known as a port and the identifier is the port number. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.
