ARP, or Address Resolution Protocol, is a network protocol used to map an IP address to a physical MAC address on a local network segment.
The purpose of ARP is to facilitate communication between devices within the same network by resolving IP addresses to MAC addresses, which are essential for data transmission at the data link layer of the OSI model.
The primary goal of ARP is to ensure efficient and accurate communication by maintaining an updated mapping of IP addresses to MAC addresses in the ARP cache.
ARP provides functions such as ARP request and ARP reply messages, which are used to dynamically discover and update mappings between IP addresses and MAC addresses on a network. These functions help devices communicate effectively by ensuring they can correctly identify each other on the local network segment.
