Status of this Memo
This memo is a status report on the parameters (i.e., numbers and
keywords) used in protocols in the Internet community. Distribution
of this memo is unlimited.
This RFC is a snapshot of the ongoing process of the assignment of
protocol parameters for the Internet protocol suite. To make the
current information readily available the assignments are kept up-to-
date in a set of online text files. This RFC has been assembled by
catinating these files together with a minimum of formatting "glue".
The authors appologize for the somewhat rougher formatting and style
than is typical of most RFCs.
We expect that various readers will notice specific items that should be
corrected. Please send any specific corrections via email to
The files in this directory document the currently assigned values for
several series of numbers used in network protocol implementations.
The Internet Assigned Numbers Authority (IANA) is the central
coordinator for the assignment of unique parameter values for Internet
protocols. The IANA is chartered by the Internet Society (ISOC) and
the Federal Network Council (FNC) to act as the clearinghouse to
assign and coordinate the use of numerous Internet protocol
The Internet protocol suite, as defined by the Internet Engineering
Task Force (IETF) and its steering group (the IESG), contains numerous
parameters, such as internet addresses, domain names, autonomous
system numbers (used in some routing protocols), protocol numbers,
port numbers, management information base object identifiers,
including private enterprise numbers, and many others.
The common use of the Internet protocols by the Internet community
requires that the particular values used in these parameter fields be
assigned uniquely. It is the task of the IANA to make those unique
assignments as requested and to maintain a registry of the currently
Requests for parameter assignments (protocols, ports, etc.) should be
Requests for SNMP network management private enterprise number

The IANA is located at and operated by the Information Sciences
Institute (ISI) of the University of Southern California (USC).
If you are developing a protocol or application that will require the
use of a link, socket, port, protocol, etc., please contact the IANA
to receive a number assignment.
