IANA is responsible for assigning TCP and UDP port numbers to specific uses. The well-known ports are those in the range 0-1023. On Unix-derived operating systems, opening a port in this range to receive incoming connections requires root privileges. Registered port numbers are those in the range 1024-49151. Port numbers in the range 49152-65535 are private or dynamic ports, 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. This article is about computer system security. ...
