TCP/IP RFCs

The standards for TCP/IP are published in a series of documents called Requests for Comments (RFCs). RFCs are an evolving series of reports, proposals for protocols, and protocol standards that describe the internal workings of TCP/IP and the Internet.

Although TCP/IP standards are always published as RFCs, not all RFCs specify standards. RFCs are authored by individuals who voluntarily write and submit a draft proposal for a new protocol or specification to the Internet Engineering Task Force (IETF) and other working groups. Submitted drafts are first reviewed by a technical expert, a task force, or an RFC editor, and then assigned a status.

If a draft passes this initial review stage, it is circulated to the larger Internet community for a period of further comment and review and assigned an RFC number. This RFC number remains constant.

If changes are made to the proposed specification, drafts that are revised or updated are circulated by using a new RFC (a number higher than the original RFC number) to identify more recent documents.

There are five status assignments for RFCs in the standards process, as shown in the following table.

Status Description

Standard protocol

An official standard protocol of the Internet.

Draft standard protocol

Under active consideration and review to become a standard protocol.

Proposed standard protocol

A protocol that in the future might become a standard protocol.

Experimental protocol

A protocol designed for experimental purposes. An experimental protocol is not intended for operational use.

Informational protocol

A protocol developed by another standards organization that is included for the convenience of the Internet community.

Historic protocol

Protocols that have been superceded or obsoleted by other protocols.

The following table shows the RFCs supported by the TCP/IP protocol and supporting services.

Obtaining RFCs

You can obtain RFCs from the RFC Editor Web site. This Web site is currently maintained by members of the Information Sciences Institute (ISI), who publish a classified listing of all RFCs. RFCs are classified as one of the following: Approved Internet standard, proposed Internet standard (circulated in draft form for review), Internet best practices, or For Your Information (FYI) document.
