Abstract
Method and system for restricting a first node in a broadcast domain of an IP (Internet Protocol) network from communicating with one or more other nodes. Each of the first node and the one or more other nodes has a respective translation table that maps an IP address to a respective physical address of all nodes with which the first node and the one or more other nodes have communicated. Embodiments of the invention describe obtaining communicated data including address resolution messages and accessing an address resolution table representative of address resolution activity in the network. Responsive to the communicated data indicating that the first node is communicating with other nodes, restricting the first node from communicating by generating and conveying a restricting address resolution message using information stored in the address resolution table, the restricting address resolution message including a substitute physical address.
