Well-known ports

Stream Control Transmission Protocol (SCTP) and the Datagram Congestion Control Protocol (DCCP) also use ports. But, usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses. However, many unofficial uses of both well-known and registered port numbers always occur. Also many of the official assignments refer to protocols that were never or are no longer in common use.

Well-known ports

Port Service Multiplexer (TCPMUX). Historic. Both TCP and UDP have been
assigned to TCPMUX by IANA, but by design only TCP is specified.
