I've had some discussions on this problem with a few people at
Microsoft. So that I'm not accidentally revealing anything that was
told to me that wasn't meant for public consumption, I'll limit myself
to what I told THEM to get the ball rolling, and leave some names out.
A good number of users turned IPv6 on in one way or another after
hearing about it, failing to get it working and not completely turning
it back off. Or it did work at one point, then later broke.
One "personal firewall system" had the foresight to realize that IPv6
might want to be firewalled as well. But just for it to install it's
v6 firewall, it turned the v6 stack on. Even if you weren't using v6.
The argument appeared to be "The user might turn v6 on later and our
firewall wouldn't have protected them".
There also were a few smaller software packages that tried to be
helpful and make sure v6 was enabled on Windows so that their v6
support worked. This seemed to break things far worse than it helped.
But, there are also people who are finding it's turned on and there
just seems to be no reasonable explanation. Embedded systems are a
great example. This is a significant problem for anyone deploying AAAA
records. This is a few months out of date, but here's a comparison of
the number of random users who have working v6 stacks to broken v6
connectivity on a highly-nontechnical popular website:
Essentially, of the users visiting the site what percentage are able
to load a 1x1 image via v6? (working clients) What percentage were
unable to load an image that had both v4 and v6 addresses? (broken
The peak starting in early 2007 seems to roughly correlate to the
uptick in Vista users, but not 1:1.
This is part of what I want to really closely document with the stuff
going on at http://www.ipv6experiment.com... which really really
really honestly is coming soon now. :)
