Abstract: System and method for multicast mapping. The system and method include a plurality of peripheral devices and a mapping server communicating with the plurality of peripheral devices over a communication network. An electronic processor of the mapping server provide a first block of information to a first peripheral device and instruct the first peripheral device to multicast the first block of information. The electronic processor receives response information from a plurality of peripheral devices. The electronic processor adds a second peripheral device to a sub-network of the first peripheral device when the response information from the second peripheral device includes the first block of information.
