1. A system comprising:
- a location server configured to monitor a register message associated with an Internet Protocol (IP) device, wherein the register message includes an internal IP address and an external IP address; and
a location database configured to store physical location information and a stored plurality of IP addresses associated with the IP device, wherein the location server determines whether at least one of the internal IP address and the external IP address of a selected message corresponds with any of the stored plurality of IP addresses associated with the IP device;
acquires physical location information corresponding to at least one of the internal IP address and the external IP address if at least one of the internal IP address and the external IP address do not correspond with any of the stored plurality of IP addresses associated with the IP device; and
provides the physical location information for use in locating the IP device.

13. A method comprising:
-
monitoring messages from an Internet Protocol (IP) device, wherein at least some of the messages provide an internal IP address and an external IP address; determining whether at least one of the internal IP address and the external IP address of a selected message corresponds with any of a stored plurality of IP addresses associated with the IP device; acquiring physical location information corresponding to at least one of the internal IP address and the external IP address if at least one of the internal IP address and the external IP address do not correspond with any of the stored plurality of IP addresses associated with the IP device, wherein the acquired physical location information is used to assist with locating the IP device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method comprising:
-
providing a plurality of Internet Protocol (IP) addresses that have a stored association with an IP device; receiving a query for physical location information, wherein the query is a result of at least one of an internal IP address and an external IP address, both of which are provided by a register message originating from the IP device, not corresponding with any of the plurality of IP addresses that have the stored association with the IP device and wherein at least one of the internal IP address and the external IP address is associated with a current physical location information of the IP device; and storing an association between the current physical location information and the IP device. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35)
