List of TCP and UDP port numbers

TCP and UDP ports are network ports.

IANA is responsible for assigning TCP and UDP port numbers to specific uses. The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports, and the Dynamic and/or Private Ports.

The Ports that are popular are those in the range 0–1023. On Unix-like operating systems, opening a port in this range to receive incoming connections requires administrative privileges, although this all might change. [ 0 ]
 The Registered Ports are those in the range 1024–49151.
 The Dynamic and/or Private Ports are those in the range 49152–65535. These ports are not used by any defined application.
IANA does not enforce this; it is simply a set of recommended uses. Sometimes ports may be used for different applications or protocols than their official IANA designation. This misuse may, for example, be by a Trojan horse, or alternatively be by a commonly used program that didn't get an IANA registered port or port range.

ICANN formed a contract with the US government on March 21, 2001, and now performs the IANA's function.

The tables below indicate a status with the following colors and tags:

 Official if the application and port combination is in the IANA list of port assignments;

 Unofficial if the application and port combination is not in the IANA list of port assignments; and
 Conflict if the port is being used commonly for two applications or protocols.
(Common) Ports 0 to 1023
 1 (Common) Ports 0 to 1023

 2 (Registered) Ports 1024 to 49151
 3 (Dynamic/Private) Ports 49152 to 65535
