Well, that's not saying quite the same thing that I was trying to say.
The /name/ on which the query is based should be independent of whether AI_ADDRCONFIG is set. However the /result/ of the query can still differ based on whether that flag is set. And if AI_ADDRCONFIG is not set, the result of the query should be the same regardless of whether the host has IPv4 access, IPv6 access, or both. This implies that the query is being done on the same name in both cases. (Actually I think that AI_ADDRCONFIG is so ambiguously defined as to be fairly useless in practice. But I also think that searching through multiple zones is a bad idea.)
