Towards Street-Level Client-Independent IP Geolocation
A highly accurate client-independent geolocation service stands to be an important goal for the Internet. Despite an extensive research effort and significant advances in this area, this goal has not yet been met. Motivated by the fact that the best results to date are achieved by utilizing additional 'Hints' beyond inherently inaccurate delay-based measurements, the authors propose a novel geolocation method that fundamentally escalates the use of external information. In particular, many entities (e.g., businesses, universities, institutions) host their Web services locally and provide their actual geographical location on their Websites. They demonstrate that the information provided in this way, when combined with network measurements, represents a precious geolocation resource.
