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.

   Port Assignments:
