RFCs

December 2016

What does RFC mean?

RFCs (Request For Comments) are a collection of documents which are referred to by the Internet community and which describe, specify and assist in the implementation, standardization and discussion of the majority of norms, standards, technologies and protocols related to the Internet and networks in general.

Who writes these RFCs?

The TCP/IP protocol suite represents a collection of norms drawn up by an organization called the IETF (Internet Engineering Task Force). This organization officially publishes their reports in the form of requests, available to all, making it possible to clarify a great number of subjects relating to TCP/IP.

Each of these documents represents a specification proposal which can be made obsolete at any time by a new RFC document. So, RFCs are text files where the name is "rfcxxxx.txt" where xxxx is a number incremented for each new RFC. There are currently more than 2000, representing a size of approximately 130MB (25MB once compressed). However a number of these files have been replaced by more recent files.

In reality, anyone can write a RFC and submit it to the IETF by sending it to the coordinator: rfc.editor@rfc.editor.org. If it is accepted, it will appear after having been appraised by the coordinators. RFC1543, entitled instructions to RFC authors, explains how to compose an RFC.
