RFC (Request for Comments)

A Request for Comments (RFC) is a formal document published by the Internet Engineering Task Force (IETF) that defines internet standards, protocols, and best practices. Despite the informal name, finalized RFCs are authoritative technical standards — nearly every foundational internet protocol, including [[dns|DNS]] (RFC 1034/1035), [[epp|EPP]] (RFC 5730), and [[whois-protocol|WHOIS]] (RFC 3912), is defined by an RFC. RFCs go through a proposal and review process before becoming standards.
