Various systems and methods are disclosed for providing support for responding to location protocol queries within a network node. One such method involves associating a location with a network identity by associating a network port with a network identity and also associating the network port with the location. The association between the network port and the network identity is created in response to a network identity, which can include an IP address, being assigned to a device coupled to the network port by an identity protocol such as DHCP. The packet is sent in response to detecting a request for the device's location. The method can be performed by various devices, including a first hop node coupled to the device, a location server, and an identity server.
