Abstract
Geolocation plays a critical role in understanding the Internet. In
this work, we analyze and fix operator-misreported geolocation.
Using DNS root servers to detect speed of Internet violations, we
conservatively infer that at least 2% of vantage points in the largest
community-vantage point collection, RIPE Atlas, were not located
at their operator-reported geolocation between January 2019 and
April 2026. To increase the accuracy of future studies that use
operator-reported geolocation, we open source our simple methodology, implement a reporting campaign of violating probes within
RIPE, work with operators to fix the misreported geolocations, and
release a continually updated dataset of RIPE vantage points that
likely misreport geolocation.
