If the remote client is IPv6 capable will it ignore the AAAA information because it was only able to get the query answered via IPv4? I believe this is what you're saying - again, just looking to clarify ;)
Um, no, what I'm saying is actually the opposite. How the client
receives the address records has nothing to do with what it does with
them. If the client is IPv6-capable, and receives AAAAs, it will use
them. The client does not even know how the resolving nameserver
retrieved the records, nor could it find out.
... and that's just a little bit of history repeating.
