Which seems a bit far afield from reality to me. Yes, there are lots of folks with IPv6 connectivity and v4-only recursive DNS servers. I don't think ISPs will have problems setting aside a handful of IPv4 addresses for authoritative DNS infrastructure to work around this until v6 transport in recursive DNS servers is common enough.
Dave, I think part of the point of this is to discover gotchas with our current infrastructure. For example, while diagnosing why I couldn't get onlyv6.com to resolve on one of my name servers but the others worked fine, I discovered that PowerDNS Recursor won't use an IPv6 address for outgoing queries unless you actually give it: query-local-address6= One of my name servers had it, the other didn't, hence I was getting failures on one and success on the other. Its little config issues like that that can crop up weeks/months/years later and make life difficult. Now that I'm a Xen shop, I design domUs to last years at a time rather then rebuilding them constantly. Being able to shunt stable and reliable domU hosts to new dom0 machines when they come up is a great thing, and makes my life alot easier. :) -- Brielle Bruns The Summit Open Source Development Group http://www.sosdg.org / http://www.ahbl.org
