Definition: RFC documents have been used on the Internet for more than 30 years. Researchers from universities and corporations publish these documents to solicit feedback on new technologies for the Internet. Most popular networking technologies like IP and Ethernet have been historically documented in RFCs.

The very first RFC, RFC 1, was published in April 1969. Although the "host software" technology discussed has long since become obsolete, documents like this one offer a very interesting glimpse into the early days of computer networking. Even today, the plain text format of the RFC remains essentially the same as it has since the beginning.

As the basic technologies of the Internet have matured, and the Internet has grown to include many non-technical people, the need for RFCs has diminished. Yet a few RFCs are still being produced for leading-edge research in Internet-based networking.
