Abstract

Methods and systems are described for resolving location information to a network identifier. In one embodiment, a method includes receiving information identifying a geospatial query region. The method also includes generating a query message including an outside-scope, unicast identifier identifying a zone corresponding to a zone region at least partially present in the query region. The method also includes sending the query message to a border node having an outside network interface for receiving the query message and an inside network interface in a network path including a network interface in the zone. The method also includes receiving a response identifying a node having a network interface in the zone.
