What is an RFC?
An RFC is a document describing the standards that make the Internet work.
An RFC starts life as an Internet Draft. The Internet Draft is proposed to the IETF, whereupon voting and modification occurs until it either becomes obsolete due to lack of interest or is accepted by the IESG, whereupon it is assigned an RFC number and published as an RFC.
The process by which an RFC is produced is described in detail in RFC 2026.
Further information on the RFC documents and the IETF, the body that produces them, can be had at http://www.rfc-editor.org, the home of the RFC Editor. While the RFC Editor was once a single individual, the legendary Jon Postel, it is now a group funded by the Internet Society.
