Well Known Port Numbers

The following description of port number assignments for Internet Protocol (IP) communication is taken from the Internet

Assigned Numbers Authority (IANA) web site (www.iana.org).

“The Well Known Ports are assigned by the IANA and on most systems can

only be used by system (or root) processes or by programs executed by

privileged users. Ports are used in the TCP [RFC793] to name the ends of

logical connections which carry long term conversations. For the purpose of

providing services to unknown callers, a service contact port is defined. This list

specifies the port used by the server process as its contact port. The contact port

is sometimes called the "well-known port". To the extent possible, these same

port assignments are used with the UDP [RFC768]. The range for assigned ports

managed by the IANA is 0-1023.”

Well-known port numbers especially pertinent to MultiVOIP operation are listed below.
