IP geographical location range inference method based on router location estimation

IP geolocation technology is very important for many network services. However, the existing IP geolocation methods can not accurately give the error range of geolocation results, and it is difficult to meet the actual geolocation needs. This paper proposed a new IP location range inference method based on router location estimation (RLG). The first step is to infer the location of the router according to the delay between the landmark and the router, and the next step is to infer the location range of the target according to the delay between the target and the router. Experiments based on 7045 landmarks show that RLG can improve the geolocation accuracy while estimating the geolocation error. Compared with SLG, Hop-Hot and DDG methods, the geolocation errors of this method are reduced by 53.1%, 45.6% and 38.7% respectively.
