The registered ports are not controlled by the IANA and on most systems can be used by user processes or programs. Registered ports between 1024 and 5000 are also referred to as the ephemeral ports. Although the IANA cannot control uses of these ports, it does register or list uses of these ports as a convenience to the TCP/IP community. To the extent possible, these same port assignments are used with UDP. The registered ports are in the range 1024 – 65535.
This list specifies the port used by the Windows NT Server and Windows NT Workstation server process as its contact port for services and third-party software.
Note
Programs that use Remote Procedure Call (RPC) to communicate can randomly select a registered port above 1024.
