List of TCP and UDP port numbers From Wikipedia, the free encyclopedia Jump to: navigation, search 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.[1] Contents • [hide]1 Table legend • 2 Well- known ports: 0–1023 • 3 Registe red ports: 1024– 49151 • 4 Dynami c and/or private ports: 49152– 65535 • 5 See also • 6 Referen ces • 7 Externa l links [edit] Table legend Color coding of table entries Official Port/application combination is registered with IANA Unofficial Port/application combination is not registered with IANA Conflict Port is in use for multiple applications [edit] Well-known ports: 0–1023 Port Description Status 0/TCP,U Reserved Official DP 1/TCP,U TCP Port Service Multiplexer Official DP 2/TCP,U Management Utility Official DP 3/TCP,U Compression Process Official DP 5/TCP,U Remote Job Entry Official DP 7/TCP,U Echo Official DP 9/TCP,U Discard Official DP 11/TCP, Active Users Official UDP 13/TCP, DAYTIME -
