Some root-servers now have IPv6 addresses.  Until I started writing this, 
I was under the impression that all did, but according to 
ftp://ftp.internic.net/domain/named.root (which is the authoritative 
source for the root-servers list), only A.ROOT-SERVERS.NET, 
F.ROOT-SERVERS.NET, H.ROOT-SERVERS.NET, I.ROOT-SERVERS.NET, 
J.ROOT-SERVERS.NET, K.ROOT-SERVERS.NET, L.ROOT-SERVERS.NET and 
M.ROOT-SERVERS.NET have IPv6 addresses.

Are you saying that Bind cannot connect to DNS root-servers over IPv6? 
What other functionality is it missing?  Certainly we run a virtual server 
on an IPv6 connection that also runs an authoritative DNS server for those 
domains and we've experienced no problems.

I'll be the first to admit that I'm not fully up on IPv6 stuff.
