ports list,descriptions,library, 21500 udp/tcp port numbers[960-1059]

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.
A port is a number used to uniquely identify a transaction over a network by specifying not only the host, but the service. For example, you may have a single network server running many different IP services, such as Web service (HTTP), mail service (SMTP), LPD, AFP over TCP, and file transfer (FTP). When clients attempt to connect to your server they need your IP address, but the clients also need to indicate which service they want to communicate with so that the data can be sent to the appropriate server application. The port number is what uniquely identifies that service on that host, what's why sometimes we can see port conflicts.
