Appendix B – TCP/UDP Port
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.
