What is an IP lookup useful for?
Checking where a suspicious login attempt came from, verifying that your VPN exit is where it claims to be, debugging geo-blocked content, or seeing what a server's registration data says about it. The lookup reads public geolocation records — it never contacts the address.
Why do different sites show different locations for the same IP?
Geolocation databases are compiled independently from provider registrations, routing data, and user reports, so they disagree at the city level. Country-level results are consistent and above 95% accurate.
