What is IP geolocation?
IP geolocation is the mapping of an IP address to an approximate physical location — country, region, and city — using databases that track which networks announce which ranges. It is accurate at the country level but coarse at the city level, and a VPN or proxy will geolocate to the exit server, not the user.
Geolocation databases (MaxMind, others) infer location from network registration, routing, and observed data. Accuracy is high for country, lower for city, and unreliable for users behind VPNs, proxies, or CGNAT.
A mismatch between IP geolocation and a browser's reported timezone or language is itself a VPN signal.
How IPLogs handles it
IPLogs uses MaxMind GeoLite2 for primary geo/ASN data and cross-checks browser timezone and language against it as a detection signal.
