IPv4 & IPv6 Queries

Fri Jan 6 22:48:49 UTC 2012

As others have pointed out, you configure both A and AAAA records into 
your zone for the same name, and then the client makes *separate* 
queries for each.

If you want a lot more detail on the process, check out RFC 3493, which 
describes the socket interface for IPv6, in particular the getaddrinfo() 
library routine which can fetch IPv4 and/or IPv6 addresses for a given 
node name or service name, and also RFC 3484, which goes into detail as 
to how the client will decide which source and destination addresses to 
use when communicating with other nodes, once the IPv4 and/or IPv6 
address(es) are obtained from DNS (or any other source).
