Request for comment. One of a series, begun in 1969, of numbered Internet
informational documents and standards widely followed by commercial software
and freeware in the Internet and Unix communities. Few RFCs are standards
but all Internet standards are recorded in RFCs. Perhaps the single most
influential RFC has been RFC 822, the Internet electronic mail (email)
format standard.

The RFCs issued by the IETF and its predecessors are the most well-known
series known as 'RFC', and is almost always what is meant by RFC without
further qualification; however, other organizations have in the past also
issued series called 'RFCs'.

The RFCs are unusual in that they are floated by technical experts acting on
their own initiative and reviewed by the Internet at large, rather than
formally promulgated through an institution such as ANSI. For this reason,
they remain known as RFCs even once adopted as standards.

The RFC tradition of pragmatic, experience-driven, after-the-fact standard
writing done by individuals or small working groups has important advantages
over the more formal, committee-driven process typical of ANSI or ISO.

Emblematic of some of these advantages is the existence of a flourishing
tradition of joke RFCs. Usually at least one a year is published, usually on
April Fool's Day.

The RFCs are most remarkable for how well they work - they manage to have
neither the ambiguities that are usually rife in informal specifications,
nor the committee-perpetrated misfeatures that often haunt formal standards,
and they define a network that has grown to truly worldwide proportions.

RFC 1, entitled "Host Software", was issued on April 7, 1969 by Steve Crocker.

For more details about RFCs and the RFC process, see RFC 2026, "The Internet
Standards Process, Revision 3"

A complete RFC index in text format is available from the IETF website, but
because of its length, it is impractical to include it in the Wikipedia. The
text of any particular RFC can be found by entering its number at
http://www.ietf.org/rfc.html.
