in reply to Compare Host Names

If doing serial lookups is enough for you, simply checking the results of gethostbyname should work, except for the problem of round-robin DNS.

As an alternative, the DNS modules (for example, AnyEvent::DNS) can do more lookups and in parallel. With those, you can possibly get all names for hostname entries, at least the synopsis of AnyEvent::DNS suggests so.

    Yeah, it just seems like my example compare_host_names() function would already exist. And it would probably handle round robin or other things I haven't thought of.

    If it doesn't exist, I'm gonna write it.
