About IP Address Lookup
IP lookup uses public geolocation databases to approximate the physical location of an IP address. Results reflect the ISP's registered location, not necessarily the end user's exact address.
Private IP ranges (RFC 1918):
10.0.0.0/8— Class A private range172.16.0.0/12— Class B private range192.168.0.0/16— Class C private range127.0.0.0/8— Loopback (localhost)
Data Source: Geolocation data is fetched from ipapi.co — a free, public API. Private and loopback addresses are resolved locally with no network requests.
