+3 A:

For Win32, getnameinfo().
For POSIX, gethostbyaddr().

Making a portable wrapper is left as an exercise. :)

In Java, there's InetAddress.getHostName(). Does that count? :)

Answer 3

+1 A:

If you're not using it in code (and you're not, according to an answer you posted, which should have really been an edit to your question :-), it's not a programming question.

But the answer is to use nslookup.

Thanks, @Z, I had to edit that bit in since I initially misunderstood the question.
