Should IPv6 be enabled?

Chris Muller-4
I thought we had it enabled in the 4.4 release, but I just downloaded
and checked:  we didn't.

So should we enable this at the last second of this release or first
second of next release or did it get tested all during this release
and its okay?

I’d say the latter - all I know about it comes from doing the RISC OS vm updates about a year ago and finding that the support code needed adding but wasn’t really in use. That implies a lack of testing to me. Could be wrong...

+1. We "should have" switched this on early in 4.5, but we didn't -
actually I think we did, found some problems and switched it off - but
now's not the time to switch it (back) on.

The IPv6 should *not* be enabled for general release. There are problems in the
new networking, particularly with respect to the resolver on Windows, and probably
other issues as well. It would be good if we can work on this in the next release
cycle, but for now the default should continue to be as before.

Pleas enable it after the release.
Reasoning is following:
- We use squeak in class and encourage our students to
at least try images on their own, hence, they should look into
the then-to-be-stable 4.5.
- As pointed out, our squeaksource is primarily advertised in DNS as
IPv6 (which we cannot and won’t change)
- If the IPv6 support can produce the spontaneous error as I indicated
(and have reproduced with other people at HPI), the students would just
be driven away.

I confirm, there is a problem (Cog VM MacOS X 10.6.8) as commented on your answer at
