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 0 to 65535, but only ports numbers 0
to 1023 are reserved for privileged services and are designated as “well-known ports” (Please refer to
Table 5). 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.

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, please
see the FAQs (Frequently Asked Questions) at:
