Port Numbers
ASSIGNED PORT NUMBERS
Ports are used in the TCP [31,72] to name the ends of logical
connections which carry long term conversations. For the purpose of
providing services to unknown callers, a service contact port is
defined. This list specifies the port used by the server process as
its contact port. The contact port is sometimes called the
"well-known port".
To the extent possible, these same port assignments are used with the
UDP [31,70].
The assigned ports use a small portion of the possible port numbers.
The assigned ports have all except the low order eight bits cleared
to zero. The low order eight bits are specified here.
