What’s the reverse DNS command line utility?

The commands dig and host should be what you’re looking for 😉 On *nix systems, you can use this command: dig -x [address] Alternatively, you can add +short at the end of the dig command to output only the DNS result. There’s also nslookup on both *nix and Windows systems for reverse DNS requests.

What’s the command-line utility in Windows to do a reverse DNS look-up?

ping -a w.x.y.z Should resolve the name from the IP address if the reverse lookup zone has been set up properly. If the reverse lookup zone does not have an entry for the record, the -a will just ping without a name.
