What is ARP?
ARP, or Address Resolution Protocol, is a communication protocol used for discovering the link layer address (typically a MAC address) associated with a given internet layer address (typically an IPv4 address). It operates by sending an ARP request to all devices on a network, asking the device with the specific IP address to respond with its MAC address. This allows devices to communicate on the local network without needing to know each other's physical addresses beforehand.
