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. 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. The tables below indicate a status with the following colors and tags: __TOC__
(Common) Ports 0 to 1023 (Registered) Ports 1024 to 49151 (Dynamic/Private) Ports 49152 to 65535 By definition, no ports can be officially registered in the Dynamic Ports range. | ||||||||
