Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining geographical locations of devices. One of the methods includes obtaining a first network address of a first device; obtaining first route information associated with at least one data transmission between the first source network address and a first network address; obtaining a second network address associated with a second device; obtaining second route information associated with at least one data transmission between a second source network address and the second network address; obtaining an estimate for geographical location of the second device; determining a first latency distance between the first network address and the second network address based on the first and second route information; and estimating a geographical location of the first device based on the estimate for geographical location of the second device and the first latency distance. |
