Abstract

The proliferation of online services comprised of globally spread microservices has security and performance implications. Understanding the underlying physical paths connecting end points has become important. This paper investigates the accuracy of commonly used IP geolocation approaches in geolocating end-to-end IP paths. To this end, we perform a controlled measurement study to collect IP level paths. We find that existing databases tend to geolocate IPs that belong to networks with global presence and those move between networks erroneously. A small percentage of IP geolocation disagreement between databases results in a significant disagreement when geolocating end-to-end paths. Geolocating one week of RIPE traceroute data validates our observations.
