At least one data collection operation is performed to obtain information pertaining to a network address. The retrieved information is processed to identify a plurality of geographic locations potentially associated with the network address, and to attach a confidence factor to each of the plurality of geographic locations. An estimated geographic location is selected from the plurality of geographic locations as being a best estimate of a true geographic location of the network address, where the selection of the estimated geographic location is based upon a degree of confidence-factor weighted agreement within the plurality of geographic locations.

* US Patent [http://patft.uspto.gov/netacgi/nph-Parser?Sect1PTO2&Sect2HITOFF&p1&u%2Fnetahtml%2FPTO%2Fsearch-bool.html&r1&fG&l50&co1AND&dPTXT&s1herringshaw&s2geolocation&OSherringshaw+AND+geolocation&RS=herringshaw+AND+geolocation 7,072,963] describes a method and a system to perform geolocation activities relating to a network address. A database of network addresses, and associated geographic locations, is maintained. A query, including a network address, is received against the database for a geographic location associated with the network address. Information, concerning the query received against the database, is logged. Geolocation activities relating to at least the network address are modified based on the logged information.
