A registered port is a network port (a sub-address defined within the Internet Protocol, in the range 1–65535) 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; ports with numbers greater than those of the registered ports are called dynamic and/or private ports.

  • ports 0~1023 - well known ports
  • ports 1024~49151 - registered port: vendors use for proprietary applications
  • ports > 49151 - dynamic / private ports
