ASSIGNED NUMBERS
This Network Working Group Request for Comments documents the currently
assigned values from several series of numbers used in network protocol
implementations. This RFC will be updated periodically, and in any case
current information can be obtained from Jon Postel. The assignment of
numbers is also handled by Jon. If you are developing a protocol or
application that will require the use of a link, socket, etc. please
contact Jon to receive a number assignment.

Most of the protocols mentioned here are documented in the RFC series of
notes. The more prominent and more generally used are documented in the
Protocol Handbook [1] prepared by the Network Information Center (NIC).
In the lists that follow a bracketed number, e.g. [1], off to the right
of the page indicates a reference for the listed protocol.

Assigned Numbers
Port or Socket Numbers
ASSIGNED PORT or SOCKET NUMBERS
Ports are used in the TCP [46] and sockets are used in the AHHP [1,3]
to name the ends of logical connections which carry long term
conversations. For the purpose of providing services to unknown
callers a service contact socket is defined. This list specifies the
port or socket used by the server process as its contact socket. In
the AHHP an Initial Connection Procedure ICP [1,34] is used between
the user process and the server process to make the initial contact
and establish the long term connections leaving the contact socket
free to handle other callers. In the TCP no ICP is necessary since a
port may engage in many simultaneous connections.
The assigned ports/sockets use a small part of the possible
port/socket numbers. The ports/assigned sockets have all except the
low order eight bits cleared to zero. The low order eigth bits are
specified here.
