Abstract:
1. A method of determining a geographic location of a requesting node, the method comprising: identifying a stored geographic location associated with the requesting node; determining a number of hops between a router from which the stored geographic location was recorded and the requesting node; receiving an indication of a number of routers within a geographic region that includes the stored geographic location; selecting a threshold number of hops corresponding to the geographic region based at least in part on the number of routers within the geographic region; identifying the stored geographic location as a regional indication of the geographic location for the requesting node if the number of hops exceeds the threshold number of hops; determining a specific geographic location associated with the requesting node in response to the identification of the stored geographic location as a regional indication of the geographic location for the requesting node; updating a database to identify the specific geographic location as a primary geographic location if the specific geographic location is located within a predefined radius of the stored geographic location; and updating the database to identify the specific geographic location as an alternate goegraphic location if the specific geographic location is located outside of the predefined radius of the stored geographic location.
