Arping

Arping

arping is a computer program which is similar in function to ping, but it operates using Address Resolution Protocol (ARP) instead of Internet Control Message Protocol. As such, arping is only usable on the local network, and in some cases the response will be coming, not from the arpinged host, but rather from an intermediate system that engages in proxy ARP (such as a router).There are two arping implementations. One is part of Linux iproute2, is Linux-only, and cannot currently ask who has what MAC address. The other arping implementation by Thomas Habets uses libpcap and libnet to be platform independent, and works on lots of UNIX-based OSs and even Windows.

Example arping (iputils version) session:

ARPING 192.168.39.120 from 192.168.39.1 eth0Unicast reply from 192.168.39.120 [00:01:80:38:F7:4C] 0.810msUnicast reply from 192.168.39.120 [00:01:80:38:F7:4C] 0.607msUnicast reply from 192.168.39.120 [00:01:80:38:F7:4C] 0.602msUnicast reply from 192.168.39.120 [00:01:80:38:F7:4C] 0.606msSent 4 probes (1 broadcast(s))Received 4 response(s)

Arping from T.Habets: arping2 00:01:80:38:F7:4C arping2 192.168.39.120

Trying to ping a MAC address will use an ICMP packet, which not all hosts actually respond to.
