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