Registered port

Registered port

A "port", in this context, is essentially a sub-address defined within the Internet Protocol. The range of valid ports is 1–65536. A registered port is one assigned by the Internet Corporation for Assigned Names and Numbers (ICANN) to a certain use. Each registered port is in the range 1024–49151.

Since 21 March, 2001 the registry agency is ICANN; before that time it was IANA.

Ports with numbers lower than those of the registered ports are called "well known ports"; port with numbers greater than those of the registered ports are called "dynamic and/or private ports".
