The tool uses a multi-phase approach: detecting continent first with 5 probes per continent, then narrowing down to country with 50 probes, followed by US state detection, and finally city-level resolution. It leverages Globalping's network of 3000+ community-hosted probes and uses traceroute instead of ping to avoid ICMP blocking issues. The approach successfully replicates commercial geolocation services' results, correctly identifying VPN server locations that providers misrepresent in public databases. The tool is open source and can run unauthenticated with 50 probes per measurement, though accuracy improves with more probes. ## Full article daily.dev links to this article rather than hosting it.
