                            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, port, protocol,
or network number 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 [17] prepared by the Network Information Center (NIC).
Some of the items listed are undocumented.  In all cases the name and
mailbox of the responsible individual is indicated.  In the lists that
follow a bracketed entry, e.g. [17,iii], at the right hand margin of the
page indicates a reference for the listed protocol, where the number
cites the document and the "iii" cites the person.
