Address Resolution Protocol (ARP) serves to map IP addresses to their corresponding MAC (Media Access Control) addresses within a local network. When a device needs to communicate with another device on the same network, ARP broadcasts a request packet asking, "Who has this IP address?" The device with the matching IP responds with its MAC address, allowing the original device to establish a direct connection. Additionally, ARP maintains a cache of these mappings to reduce the need for repeated requests, thereby enhancing network efficiency.
Dynamic ARP table entries are created whne a client makes an ARP request that cannot be satisfied by data already in the ARP table.
