1. A method for sending packets in a network, the method comprising: receiving, at a computing device, a set of addresses in a first segment of the network, wherein the set of addresses is a subset of all addresses in the first segment of the network; receiving, at a computing device, a packet from the network, the packet having a source address in the first segment of the network and a destination address in a second segment of the network; determining whether the source address of the packet is one of the addresses included in the received set of addresses; and based on a determination that the source address is one of the addresses included in the received set of addresses, bridging the packet from the first segment to the second segment.
