This memo is an official status report on the protocols used in the

Internet community. Distribution of this memo is unlimited.


This RFC identifies the documents specifying the official protocols

used in the Internet. Comments indicate any revisions or changes


To first order, the official protocols are those specified in the

"DDN Protocol Handbook" (DPH), dated December 1985 (this is a three

volume set with a total thickness of about 5 inches).

Older collections that include many of these specifications are the

"Internet Protocol Transition Workbook" (IPTW), dated March 1982; the

"Internet Mail Protocols", dated November 1982; and the "Internet

Telnet Protocols and Options", dated June 1983. There is also a

volume of protocol related information called the "Internet Protocol

Implementers Guide" (IPIG) dated August 1982. An even older

collection is the "ARPANET Protocol Handbook" (APH) dated

January 1978. Nearly all the relevant material from these

collections has been reproduced in the current DPH.

The following material is organized as a sketchy outline. The

entries are protocols (e.g., Transmission Control Protocol). In each

entry there are notes on status, specification, comments, other

references, dependencies, and contact.

The STATUS is one of: required, recommended, elective,

experimental, or none.

The SPECIFICATION identifies the protocol defining documents.

The COMMENTS describe any differences from the specification or

problems with the protocol.

The OTHER REFERENCES identify documents that comment on or expand

on the protocol.
