}High-Performance IP Address Intelligence
IP Geolocation & Lookup API is an IP intelligence API (<50ms latency) that resolves any IPv4 or IPv6 address into geographical metadata (country, city, latitude/longitude), ISP carrier, Autonomous System Number (ASN), timezone, and proxy/VPN threat detection flags.
Accurate IP geolocation and network threat detection are critical for modern web applications. Whether you are routing visitors to regional storefronts, preventing fraudulent credit card signups, enforcing digital rights management (DRM) geo-restrictions, or enriching security log pipelines, our IP Geolocation API delivers comprehensive IP metadata in sub-50 milliseconds.
Every API response includes detailed geographic, network, and security data points: country name, two-letter ISO country code, region/state, city, zip postal code, precise latitude/longitude coordinates, IANA timezone string, Internet Service Provider (ISP), Autonomous System Number (ASN), organization name, and boolean threat flags for VPN, proxy, cloud hosting, and mobile network traffic.
Our IP database is synchronized daily with Regional Internet Registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC) and BGP global routing announcements, ensuring >99.8% country accuracy and up-to-date carrier mapping.
