List of TCP and UDP port numbers

Template:Short description

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,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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.

Template:No	Described protocol is not assigned by IANA for this port, standardized, specified, or widely used for such.

Well-known portsEdit

The port numbers in the range from 0 to 1023 (0 to 2¹⁰ − 1) are the well-known ports or system ports.<ref name="rfc6335">Template:Cite IETF</ref> 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.<ref>Template:Man. "... Port numbers below 1024 (so-called "low numbered" ports) can only be bound to by root ... Well-known port numbers specified by the IANA are normally located in this root-only space. ..."</ref>

Registered portsEdit

The range of port numbers from 1024 to 49151 (2¹⁰ to 2¹⁵ + 2¹⁴ − 1) are the registered ports. They are assigned by IANA for specific service upon application by a requesting entity.<ref name="IANA" /> On most systems, registered ports can be used without superuser privileges.
