Abstract

Verifying subscriber host connectivity is disclosed. In some embodiments, a unicast address resolution protocol (ARP) request is sent to a subscriber host, and based at least in part on whether a response to the request is received from the subscriber host, it is determined whether the subscriber host remains connected to a network.
