                            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, subject to the agreement between
DARPA/IPTO and DDN/PMO about number allocation, documented in Appendix A
of this RFC.  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.

The ARPANET community is making the transition form the ARPANET to the
ARPA Internet.  This has been characterized as the NCP/TCP transition
[63], although many other the protocols are involved, too.  The working
documents for the new Internet environment have been collected by the
Network Information Center (NIC) in a book entitled the "Internet
Protocol Transition Workbook" [62].

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
"Internet Protocol Transition Workbook" or in the old "Protocol
Handbook" [17] prepared by the 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.
