Hmm. You shouldn't be getting any DNS responses from any of the
AOL mail servers. They shouldn't have nameservers running on them,
and even if they did, that should be forward-only through a central
set of caching nameservers that should be able to handle on the order
of 32,000 DNS queries per second.
If you get DNS responses from the AOL nameservers which have
different reverse DNS for IP addresses than the forward resolution,
then that is an artifact of the multi-homed nature of the machines
and certain legacy issues.
