Internet Standard

Internet Standard (often abbreviated STD) is the highest maturity level in the Internet Engineering Task Force (IETF) standards track for Internet protocol specifications. Internet Standards are published as one or more Request for Comments (RFC) documents and are additionally assigned an STD number that identifies the standard as a whole (as distinct from the RFC document number).

The Internet Standards Process is defined in a series of IETF Best Current Practice documents, including RFC 2026 and RFC 6410. Not all RFCs are Internet Standards; RFCs may also be informational, experimental, or otherwise outside the standards track.
