1. A method for proxy address resolution protocol processing, the method comprising:
sending, by a first subscriber device, an address resolution protocol processing broadcast to obtain an address for a second subscriber device, wherein the first subscriber device and the second subscriber device are in isolated routing prefix domains within a routing prefix;
receiving, by the first subscriber device from a gateway, a second subscriber device proxy address for the second subscriber device, wherein the second subscriber device proxy address is at least locally unique to a routing prefix domain associated with the first subscriber device; and
communicating, between the first subscriber device and the second subscriber device via the gateway, wherein the first subscriber device sends data using the second subscriber device proxy address and the gateway updates the data with a first subscriber device proxy address for the first subscriber device, and wherein the first subscriber device proxy address is at least locally unique to a routing prefix domain associated with the second subscriber device.
