Abstract

A number of ICMPv4 [RFC0792] message types have been specified over the years. A number of these message types have become obsolete in practice, but have never been formally deprecated. This document deprecates such ICMPv4 message types, "cleaning up" the corresponding IANA registry. Additionally, it updates RFC 792 and RFC 950, obsoletes RFC 1788, and requests the RFC Editor to change the status of RFC 1788 to Historic.
