ABSTRACT:
One feature provides a method for encoding geolocation information into a next-generation internet protocol (IP) address, such as IPv6, to facilitate distribution of geolocation information among networked devices. A request for an IP address assignment is received from a network device. The geographical location for the network device is obtained. An IP address is assigned or generated that includes the geographical location. The assigned IP address is then provided to the network device. By encoding the geolocation information of a first network device into the IP address assigned to the first network device, other network devices are able to readily obtain the geographical location of the first network device. This method propagates geolocation information for network devices as part of the IP address, thus avoiding the need for separate geolocation distribution messaging. As the network device moves, its IP address is changed to update its geographical location information.
