I've read where AD DNS will sort replies to A record requests based on the IP address of the caller. The idea being that if multiple A records exist for a name, the first in the list will be "closest" to the caller. Makes sense, but I've never seen any documentation on how the comparison is done.
Does the DNS server do a simple IP subnet match (same subnet = close, different subnet = not close)? Or, is the DNS server site aware so that it will sort first an address in the same site even if it's a different subnet?
