Claim Text:
1. A system for discovering nodes of a network, comprising: a communication interface configured to a processor coupled with the communication interface and configured to use the received communication error replies to the multicast packet to determine a listing of all nodes of at least the multicast group of the network, wherein determining the listing of all nodes of at least the multicast group of the network includes discovering the nodes of the network that have not been previously discovered to be in the multicast group by identifying that a previously undiscovered node provided a communion error response in direct reply to the Internet Protocol version 6 multicast packet requiring the receiver of the packet to provide the communion error response; wherein the multicast group was determined by incrementing or decrementing a previous multicast group number in response to a determination that a response associated with the previous multicast group number was received and the listing of all nodes includes identifications of all nodes belonging to the previous multicast group number in addition to identifications of all nodes belonging to the multicast group.
