How to Use the Arp -a Utility

The Address Resolution Protocol (Arp) allows a host to find the media access control address of a host on the same physical network, given the IP address of the host. To make ARP efficient, each computer caches IP-to-media access control address mappings to eliminate repetitive Arp broadcast requests.

You can use the arp -acommand to view the Arp table entries on a specified host. The arp command is useful for viewing the Arp cache and resolving address resolution problems.
