The official document by which the Internet Activities Board (IAB) and the Internet Engineering Task Force (IETF) publish standards, protocols, best practices, or other information relative to the operation of the Internet. The format dates to the early days of the ARPANET in which authors circulated hard copies of their proposals to their colleagues and requested their comments. In the more formal context of contemporary Internet administration, requests for comments actually are made in an Internet Draft document. See also ARPANET, IAB, IETF, and Internet.
(Request For Comments) A document that describes the specifications for a recommended technology. Although the word "request" is in the title, if the specification is ratified, it becomes a standards document. Not all RFCs become standards; some are designated indefinitely with Informational or Experimental status. RFCs are used by the Internet Engineering Task Force (IETF) and other standards bodies. First used during the creation of the ARPAnet protocols back in the 1970s, the IETF has published more than 3,000 RFCs, all of which can be looked up at www.ietf.org/rfc.html. See Internet Engineering Task Force.
