Passport: Enabling Accurate Country-Level Router Geolocation using Inaccurate Sources
When does Internet traffic cross international borders? This question has
major geopolitical, legal and social implications and is surprisingly difficult
to answer. A critical stumbling block is a dearth of tools that accurately map
routers traversed by Internet traffic to the countries in which they are
located. This paper presents Passport: a new approach for efficient, accurate
country-level router geolocation and a system that implements it. Passport
provides location predictions with limited active measurements, using machine
learning to combine information from IP geolocation databases, router
hostnames, whois records, and ping measurements. We show that Passport
substantially outperforms existing techniques, and identify cases where paths
traverse countries with implications for security, privacy, and performance
