I remain strongly opposed to reclassifying 6to4 as Historic unless/until a
better alternative appears. Putting an explanation inside an informational
document doesn't change that opposition.
I also continue to believe that the -historic draft has too many misstatements
and misleading statements in it, that the entire motivation for the draft is
seriously flawed, and that it should not be published in anything like its
current form.
But I agree that 6to4 should be off by default, mostly because there's no good
off-the-shelf way to have 6to4 automatically disabled when a host or router
connects to a network that is using NAT but not using RFC 1918 addresses.

Folks,
After some discussion, the IESG is attempting to determine whether there is
IETF consensus to do the following:
- add a new section to draft-ietf-v6ops-6to4-to-historic
- publish draft-ietf-v6ops-6to4-to-historic as INFORMATIONAL
draft-ietf-v6ops-6to4-to-historic will obsolete RFCs 3056 and 3068 and
convert their status to HISTORIC. It will also contain a new section
describing what it means for RFCs 3056 and 3068 to be classified as HISTORIC.
The new section will say that:
- 6-to-4 should not be configured by default on any implementation (hosts,
cpe routers, other)
- vendors will decide whether/when 6-to-4 will be removed from
implementations. Likewise, operators will decide whether/when 6-to-4 relays
will be removed from their networks. The status of RFCs 3056 and 3068 should
not be interpreted as a recommendation to remove 6-to-4 at any particular
time.
draft-ietf-v6ops-6to4-to-historic will not update RFC 2026. While it
clarifies the meaning of "HISTORIC" in this particular case, it does not set
a precedent for any future case.
Please post your views on this course of action by August 8, 2011.
