TCP/UDP Port Numbers

TCP/UDP port numbers are included in packets sent over a network using either the TCP or the UDP transport layer protocol. The TCP/UDP port number indicates how to apply an application layer protocol to the data at the receiving end. For example, port 25 is associated with the SMTP application protocol, and port 23 is associated with the Telnet application protocol. A single application may use several different TCP/UDP port numbers for various kinds of communication functions it performs.

There are three ranges of TCP/UDP port numbers:

•TCP/UDP ports 0 - 1023 - Well Known Port Numbers. Well Known Port Numbers represent basic network services that are widely available using standard TCP/UDP port numbers. Well Known Port Numbers are assigned by the IANA (Internet Assigned Numbers Authority). On many platforms, the ways in which these TCP/UDP ports can be used are restricted by the system.

•TCP/UDP ports 1024 - 49151 - Registered Port Numbers. Registered Port Numbers represent specific network services that have been registered by the IANA at the request of a vendor or organization.

•TCP/UDP ports 49152 - 65535 - Private Port Numbers. Private Port Numbers are available for unrestricted use by applications. The same Private Port Number might be used for different purposes by different applications.
