Dan Kaminsky countering Paul's claims:
"First, while there are indeed a couple underprovisioned name
servers, there's far more that have lots and lots of slack capacity.
You need slack capacity to deal with shock load. The networks that
would fail because of Vista's release, would fail because of a three
Second, Vista's not getting deployed all at once. This is no service
pack that's deployed to a hundred million desktops via Windows
Update! Mockapetris is correct in that there will be a noticable
increase in DNS traffic, but that increase will be spread out over
the course of a couple years. Slow increases like this tend not to
cause the sort of catastrophic failure that Mockapetris refers to.
Finally, and most importantly (in the sense that Mockapetris should
know better): Most of the work done to service the IPv6 request, is
cached and available to service the IPv4. To complete a DNS lookup,
you have to locate a particular server, known as the authoritative
server for a domain. The same authoritative server that hosts the
IPv6 (AAAA) record also hosts the IPv4 (A) record. So even if Vista
sends twice the traffic, the upstream nameserver is certainly not
experiencing twice the load."
