Description: The Group Address Resolution Protocol (GARP) is a network protocol used to resolve addresses in a group context, facilitating communication between devices on a local network. GARP allows a device to send information about its group address to other devices on the network, helping to establish and maintain the association between IP addresses and MAC addresses in environments that use group addresses. This protocol is particularly relevant in networks that implement the Internet Protocol (IP) multicast and in local area network (LAN) configurations where communication between multiple devices is required. GARP operates at the data link layer of the OSI model, meaning it handles data transmission between devices on the same physical network. Its operation is fundamental for the correct functioning of network protocols that rely on group communication. In summary, GARP is a key component in address management in local networks, ensuring that devices can communicate efficiently and effectively in a group environment.
