CLI Tool for IP Geolocation and Analysis of VPN Provider Location Spoofing
By
jimaek
Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
A developer created a CLI tool for IP geolocation that can resolve IP addresses to country, US state, and city levels. The tool confirms findings from ipinfo, which recently exposed how VPN providers fake IP geolocation by intentionally providing incorrect location data to regional internet registries and geo database providers via geofeeds. The article discusses the technical approach and implications of this discovery.
Key quotes
· 4 pulledI made a CLI tool that can resolve an IP address to a country, US state and even a city.
VPN providers don't actually maintain a crazy amount of infrastructure in hundreds of countries.
They simply fake the IP geolocation by intentionally providing wrong location data to ARIN, RIPE, and Geo DB providers via geofeeds.
It works well and confirms ipinfo's findings.
