Port Numbers


                         ASSIGNED PORT NUMBERS

   Ports are used in the TCP [33,78] 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 [33,76].

   The assigned ports use a small portion of the possible port numbers.
   The assigned ports have all except the low order eight bits cleared
