Experimental Values In IPv4, IPv6, ICMPv4, ICMPv6, UDP, and TCP Headers
RFC 4727, “Experimental Values In IPv4, IPv6, ICMPv4, ICMPv6, UDP, and TCP Headers”, is a Proposed Standard document published in November 2006 by B. Fenner. The canonical text is published by the RFC Editor.
Abstract
When experimenting with or extending protocols, it is often necessary to use some sort of protocol number or constant in order to actually test or experiment with the new function, even when testing in a closed environment. This document reserves some ranges of numbers for experimentation purposes in specific protocols where the need to support experimentation has been identified, and it describes the numbers that have already been reserved by other documents. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
