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

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,
