The IESG has approved the following document: - 'Formally Deprecating Some ICMPv4 Message Types' (draft-gp-obsolete-icmp-types-iana-01.txt) as Proposed Standard This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Ronald Bonica. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-gp-obsolete-icmp-types-iana/ Technical Summary A number of ICMPv4 message types have become obsolete in practice, but have never been formally deprecated. This document deprecates such ICMPv4 message types, thus cleaning up the corresponding IANA registry. Additionally, it updates RFC792 and RFC950, obsoletes RFC1788, and requests the RFC Editor to change the status of RFC1788 to "Historic". Working Group Summary This document was not considered by any IETF Working Group. It was generated as an individual submission when it was realized that in obsoleting unused ICMP code points certain RFCs would also need to be updated or obsoleted. Document Quality This document does a clear job of laying out the changes it makes. As it is marking unused protocol identifiers as deprecated, there is no implementation of this document, nor of most of the items it references. Personnel Joel Halpern is the Docment Shepherd for this Individual Submission document. Ron Bonica is the sponsoring AD.
