In internetworking and computer network engineering, Request for Comments (RFC) documents are a series of memoranda encompassing new research, innovations, and methodologies applicable to Internet technologies.

Through the Internet Society, engineers and computer scientists may publish discourse in the form of an RFC memorandum, either for peer review or simply to convey new concepts, information, or (occasionally) engineering humor. The Internet Engineering Task Force (IETF) adopts some of the proposals published in RFCs as Internet standards.
