How accurate are IP geolocation services?
(WorldNews Sweden)

The proliferation of online services comprising globally-spread micro services has security and performance implications. For this reason, understanding the underlying physical paths connecting end points has become important and given rise to numerous approaches for inferring the location of infrastructure IP addresses. Our recent study at SimulaMet sought to investigate the accuracy and difference between these approaches. We found there are inaccuracies in the existing geolocation approaches when mapping end-to-end Internet paths to physical locations, with 77% of IPv4 and 65% of IPv6 economy-level mappings missing at least one economy along the path of our dataset. We also found that...
