Several thousand hours of IPv6 usage on XP and Windows 7 prompts me to wholly agree with Brian. The way DNS works now fits 95% plus of the transition environments. The proposed DNS hack will be obsolete before it can be passed thru the IETF anyway since IPv6 usage is growing exponentially during 2010. Comcast alone will account for 50% of the transition market during this calendar year. And they have hard dates for completing IPv6 implementation during 2010. So don't break DNS for the 95% using it successfully today for the 5% that are not working today without manual intervention. Carroll Perkins

I prefer the current situation, where occasionally I have to disable IPv6 manually due to being on an IPv6-broken network where DNS serves up AAAA records and my regular tunnel is too slow. This seems OK, since people using v6 on XP are normally doing so as conscious early adopters. I do think that Google's solution to this, i.e. being selective about who gets the AAAA records in the first place, is much less of hack with less harmful side effects. Surely a better hack would be for recursive resolvers in IPv6-broken networks not to serve up AAAA records at all? Tunnel users could always find another resolver.
