Abstract
Conventional efforts for estimating the geographic location (geolocation) of devices associated with particular Internet Protocol (IP) addresses typically yield woefully inaccurate results. In many cases, the estimated IP geolocations are on the wrong continent. Embodiments of the present technology include techniques for identifying and improving incorrect estimates based on latency measurements, Domain Name Server (DNS) information, and routing information. For example, latency measurements from multiple collectors can be used to rate the plausibility of an IP geolocation estimate and, in certain cases, to increase the accuracy of the IP geolocation estimate. DNS and routing information can be used to corroborate the estimated IP geolocation. The resulting more accurate IP geolocation estimate can be used to route Internet traffic more efficiently, to enforce rules for routing sensitive information, and to simplify troubleshooting.
