Abstract
Systems and methods of the present disclosure provide a way to pinpoint where a target device associated with an IP address is physically located within a geographical region. Network-communication delays between landmark devices and the target device are determined and used to generate sequences capturing relative delay relationships between the landmark devices and the target device. The sequences are used to determine a ranking via a sequence-matching approach. For each pair of landmark devices, a geographical boundary that divides the geographical region into a target partition and a second partition is determined. The target partition includes a first landmark device of the pair and the second partition includes a second landmark device of the pair. The target device is located where the target partitions for the pairs overlap. Network tomography can be applied to increase accuracy.
