Arping is an arp level ping utility which broadcasts a who-has ARP packet on the network and prints answers. Very useful when you are trying to pick an unused IP for a net that you don't yet have routing to, or to ping an ethernet address directly. Tested on Linux, {Free,Net,Open}BSD, MacOS X, and Solaris.
