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.

Release Notes: This release prints "Timeout" when pings time out, fixes a bug with -w for fractions of seconds, works around a bug in libpcap on Solaris, and implements gratuitous ARP (-U).


Release Notes: This release fixes a timing issue on BSD and adds a statistics line with min/avg/max/std-dev.


Release Notes: This release fixes a null pointer dereference introduced in version 2.10.


Release Notes: This release adds much improved and portable interface autodetection. It replaces gettimeofday() with clock_gettime() where available. It has been changed back from poll() to select() to work around a bug in Mac OS X.


Release Notes: This release adds a -D option that show dots and exclamation marks. Old Arping 1.x code has been removed. The autoconf build system is used. The Solaris timing system has been fixed. Solaris auto-find outgoing interface has been added. This release will beep when there is no reply.

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 :-(
