I recently noticed that RFC 796, Address Mappings, contains
out-of-date information, but its status has never been changed to
Historic. At the suggestion of the sunset4 WG chairs, I would like to
bring this topic up for discussion on the list. Here are the relevant
sections of the first cut of the draft I wrote:
=====
Abstract
This memo reclassifies RFC 796, Address Mappings, to Historic
status. This memo also obsoletes RFC 796.
1. Reclassification of RFC 796 to Historic
RFC 796 [RFC796] specifies formats for "classful" IPv4 addresses.
It also specifies mappings for some existing networks at the time it
was published between their "local" network representations and
IPv4 equivalents. However, "classful" addresses have been largely
superseded by CIDR [RFC4632]. Furthermore, the vast majority of
these addresses have either been reassigned to other organizations,
or are considered part of private address space [RFC1918].
Therefore, RFC 796 is reclassified to Historic status.
