Correction. Round-robin is working OK at aol. I waited 3166 seconds,
and got the same 4 MX records above, but in a different order. I'm
still learning DNS. :>)
You shouldn't have to wait for the TTL to expire, you should be
getting the round robin results for every query.
Nope. The order stays the same in the Answer Section, but it does rotate
with every query in the Additional Section. The rotation is within each
RRset, and the different RRsets seem to come and go as a unit, e.g. all
five A records for mailin-01.mx.aol.com are kept as an all-or-nothing
set. That could save some queries if we can count on this behavior.
This may be just the behavior of my local nameserver. I'll try digging the
aol server.
