To: IETF-Announce
Cc: RFC Editor , gds@gds.best.vwh.net, sunset4-chairs@tools.ietf.org
Subject: Document Action: Address mappings to Historic

The IESG has approved changing the status of the following document:
- Address mappings
  (rfc796) to Historic

This document action is documented at:
http://datatracker.ietf.org/doc/status-change-ipv4-address-mapping-classes-to-historic/

A URL of the affected document is:

Status Change Details:

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superseded by CIDR [RFC4632].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.

Personnel

  Ted Lemon is the responsible Area Director.

[Ballot comment]
Greg Skinner supplied me with the information I needed.
I leave it up to the responsible AD to decide whether he wants to update the Status Change Note.

[Ballot discuss]
I find myself wanting to have a brief Discussion about the text in the Status Change document. I rather regret that because this "move to Historic" has already taken up more time than it was worth spending on it.

"Largely superseded" means that some are still in use.
"vast majority..." means that some are still in use.

What is the status of those classful addresses when this RFC is marked as Historic? Where does one go to read a current description of their usage and for mappings of the networks that are still in use?
