Address resolution protocol is used to find the MAC address or hardware address from destination IP address through ARP request by network layer.
The Arp tool allows a user to view and modify ARP table entries on the local computer. The arp command is useful for viewing the ARP cache and resolving address resolution problems. A static entry can be added to an ARP file by issuing the arp -s < IP address > < MAC address > command. However, adding such static ARP cache entries must be used with caution as it is easy to enter the wrong MAC address for an IP address. Detecting Duplicate IP Addresses Using ARP When starting up, Windows performs a gratuitous ARP to detect any duplication with its own IP address.
