GARP (Group Address Resolution Protocol) is a networking protocol used to map an IP address to a physical machine address on a local network.
GARP Definition: GARP (Group Address Resolution Protocol) is a networking protocol used to map an IP address to a physical machine address on a local network.
GARP stands for Gratuitous Address Resolution Protocol. It is a protocol used in computer networking to map Internet Protocol (IP) network addresses to Media Access Control (MAC) hardware addresses as part of the Address Resolution Protocol (ARP) process. Gratuitous ARP is a special type of ARP packet where a device sends an ARP request or response for its own IP address, updating other devices' ARP cache with its MAC address. This helps in ensuring that network devices have accurate information about the locations of devices within the network and helps to prevent network issues by maintaining the consistency of ARP caches across all devices.
