Generally speaking, there is no way to know every name that may resolve
to a particular IP address, or set of IP addresses, without searching
every DNS zone on every DNS server in the planet, which is obviously
impractical. Using some heuristic methods, you might get lucky and
stumble across a particular name that happens to resolve to the
address(es) of interest, but there are certainly no guarantees.
Why don't you just create the round-robin name you want in one of your
own zones and use that?
