This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses,1 However, many unofficial uses of both well-known and registered port numbers occur in practice. Similarly, many of the official assignments refer to protocols that were never or are no longer in common use. This article lists port numbers and their associated protocols that have experienced significant uptake.
Table legend
Cell | Description |
---|---|
Yes | Described protocol is assigned by IANA for this port, and is: standardized, specified, or widely used for such. |
Unofficial | Described protocol is not assigned by IANA for this port, but is: standardized, specified, or widely used for such. |
Assigned | Described protocol is assigned by IANA for this port,2 but is not: standardized, specified, or widely used for such. |
No | Described protocol is not assigned by IANA for this port, standardized, specified, or widely used for such. |
Reserved | Port is reserved by IANA,2 generally to prevent collision having its previous use removed.3 4 The port number may be available for assignment upon request to IANA.3 |
Well-known ports
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports.3 They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports.5
