This is a list of notable port numbers used by protocols of the transport layer of the Internet protocol suite for the establishment of host to host connectivity.

Later, the Transmission Control Protocol TCP and the User Datagram Protocol UDP needed only one port for full duplex, bidirectional traffic. The even numbered ports were not used, and this resulted in some even numbers in the well known port number range being unassigned.
