With BIND, the hints file is used to bootstrap a nameserver such that 
it can find answers to the question "dig . NS", with attendant glue. 
Once such an answer has been received, the hints file is not used any 
more.

So editing the hints file to include AAAA records might cause the first 
query a recursive nameserver makes after boot to be carried over IPv6, 
but until there are AAAA records in the root zone, all subsequent 
queries to the root will be sent over IPv4.

It would be interesting to know what a recursive nameserver with AAAA 
records added to its hints file and no IPv4 transit would do, after it 
got an answer with no IPv6 glue from a root nameserver, though. I 
haven't tried it.
