    This is a list of Internet socket port numbers used by protocols of the Transport Layer of the Internet Protocol Suite for the establishment of host-to-host communications.
    Originally, these port numbers were used by the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), but are used also for the Stream Control Transmission Protocol (SCTP), and the Datagram Congestion Control Protocol (DCCP). SCTP and DCCP services usually use a port number that matches the service of the corresponding TCP or UDP implementation if they exist.

    I would simply post it here but it's well maintained and updated at the Wiki by several users.
