Home broadband users are real residential users with high risk-control value, though geolocation accuracy is limited (some regions share CGNAT). Risk-control advice: focus on behavioral anomalies rather than the IP itself.
Independent offline databases (ip2region vs GeoLite2) may disagree on an IP's location; both are third-party judgments for reference only. The page's primary location prefers ip2region.
Data source: ip2region+GeoLite2 (local offline databases)
