What is ARP?

ARP (Address Resolution Protocol) is a protocol used to map an IP address to a physical MAC address in a local network. It is essential for devices on a network to communicate, as it allows them to find the hardware address of another device given its IP address. It works by sending a broadcast ARP request to all devices on the network. The device with the matching IP address responds with its MAC address, which is then used to send data directly to that device.
