Example: List of some well-known and registered port numbers.
The Internet Assigned Numbers Authority (IANA) is the central coordinator for the assignment of
unique parameter values for Internet protocols. Port numbers range from 1 to 65535, but only ports
numbers 1 to 1023 are reserved for privileged services and are designated as “well-known ports”
(Please refer to Table below). The registered ports are numbered from 1024 through 49151. The
remaining ports, referred to as dynamic or private ports, are numbered from 49152 through 65535.
Examples of well-known and registered port numbers are shown below, for further information,
please see IANA’s website at:
http://www.iana.org/assignments/port-numbers
.
For help on determining which private port numbers are used by common applications on this list,
