1. A system comprising:
- a first network configured to receive IP device data from an IP device and to provide a plurality of Internet Protocol (IP) addresses of the IP device based on the IP device data, wherein the plurality of IP addresses includes an internal IP address internal to the first network and an external IP address external to the first network, the first network comprising;
a first network location server configured to determine whether the IP device has changed its location based on the plurality of IP addresses; and
a second network comprising;
a second network location database configured to store physical location information, anda second network location server configured to receive, from the first network, the plurality of IP addresses of the IP device based on the determination by the first network location server, and query the second network location database to determine physical location information of the IP device based on the internal IP address or the external IP address, wherein the physical location information of the IP device is provided to a service bureau, which is external to both the first network and the second network, for storage.

12. A method for updating location information of an IP device at a first network, the method comprising:
-
receiving IP device data information from the IP device, the IP device data including registration information and a plurality of Internet Protocol (IP) addresses, wherein the plurality of IP addresses includes an internal IP address internal to the first network and an external IP address external to the first network; determining whether the IP device has changed locations based on the plurality of IP addresses; transmitting at least one IP address of the plurality of IP addresses to a second network having a network location server when the IP device has changed locations, wherein the at least one IP address of the plurality of IP addresses correlates to a network location of the IP device and the received registration information; receiving location information from the network location server, wherein the location information correlates to the internal IP address or the external IP address associated with the IP device and assists in determining a current physical location of the IP device; and communicating the location information to a service bureau, which is external to both the first network and the second network, for updating the location information of the IP device stored at the service bureau. - View Dependent Claims (13, 14)

15. A system including a first network and a second network, the system comprising:
-
a second network location database configured to store physical location information correlated to network location information; a second network location server connected to the second network location database and the first network having a first network location server, the second network location server configured to receive a plurality of IP addresses of an IP device from the first network wherein the plurality of IP addresses includes an internal IP address internal to the first network and an external IP address external to the first network, supply the internal IP address or the external IP address to the second network location database, receive location information from the second network location database wherein the location information includes physical location information of the IP device, determine whether the physical location of the IP device can be identified based on the location information, and communicate with the first network location server based on the determination so that the first network location server can assist in locating the IP device, and wherein the location information is used for updating the location information stored at a service bureau, which is external to both the first network and the second network. - View Dependent Claims (16, 17)
