Arping – To Discover Hosts on a Computer Network. Arping is a computer software tool that is used to discover hosts on a computer network. The program tests whether a given IP address is in use on the local network, and can get additional information about the device using that address. Arping operates work at the layer 2 (or the link layer of the If you clear Window's arp cache ( arp -d ) and then try to ping the ip address, it will issue a arp broadcast.

The arping utility sends ARP and/or ICMP requests to the specified host and displays the replies. The host may be specified by its hostname, its IP address, or its MAC address. One request is sent each second. When pinging an IP an ARP who-has query is sent. When pinging a MAC address a directed broadcast ICMP Echo request is sent.
