Huh?
What are you talking about?
I can't think of any application that would need to query for NS
records for the root. This is the only place where stuff is going to
change. AAAA records have been popping up all over the rest of the DNS
hierarchy for years so this is something that applications should be
used to by now.
The fact that an IPv6 host can't talk to an IPv4 host is unavoidable
because the fact that IPv4 hosts can't talk to systems with addresses
longer than 32 bits is exactly the reason why IPv6 was created.
Hopefully we can take the edge off of that with a better version of
NAT-PT. In the mean time, you'll want to run dual stack, not IPv6-only.
