Arping

Arping is an ARP level ping utility. It's good for finding out if an IP is taken before you have routing to that subnet. It can also ping MAC addresses directly.

            Check out arping-scan-net.sh, included in arping. It
            scans an IP network for a certain MAC address. It's only
            needed for those that don't answer broadcast pings (also,
            you can try the multicast IP 224.0.0.1), but when all else
            fails, the script *will* find the box (unless it's actually
            not answering ICMP pings).

            As another comment has pointed out, that is a less capable arping, it's not the same program.
            Arping exists in debian (though currently lagging on the 1.02 version) in the package arping.
            The less capable arping from iputils is now in the package iputils-arping.

            Re: Awesome!
            Thats because you're running /sbin/arping (which is included with iputils) instead of the version you downloaded, compiled, and installed..

            uhm.. iputils..
            You do realize that arping is already part of iputils.. If you make any significant changes/improvments you should get them included in the iputils package.

            Its feature to map MAC addresses back to IP is quite
            useful. Unfortunately, that only works for machines which
            answer broadcast pings, i.e. not for windows machines :-(
