ARP (address resolution protocol) operates by broadcasting a message across a network, to determine the Layer 2 address (MAC address) of a host with a predefined Layer 3 address (IP address). The host at the destination IP address sends a reply packet containing its MAC address. Once the initial ARP transaction is complete, the originating device then caches the ARP response, which is used within the Layer 2 header of packets that are sent to a specified IP address.
ARP spoofing Attack is a type of attack in which a malicious actor sends falsified ARP messages over a local area network. This results in the linking of an attacker's MAC address with the IP address of a legitimate computer or server on the network.
