TCP and UDP Port Assignments
TCP and UDP Port Assignments |
|
Registered Ports, ports between 1024 and 49151, are listed by the IANA and on most systems can be used by applications or programs executed by users. Table C.2 specifies the port used by the server process as its contact port. The IANA registers uses of these ports as a convenience to the Internet community. To the extent possible, these same port assignments are used with UDP. The Registered Ports are in the numerical range of 1024-49151. The Registered Ports between 1024 and 5000 are also referred to as the Ephemeral Ports. The list below contains most of the port assignments that are significant to Windows 2000.
