Determine location by IP address or domain
IP geolocation determines the physical location of a device by its IP address. Our tool uses a local MaxMind GeoLite2 database updated weekly, providing high accuracy for country, region, city, ISP, and autonomous system (AS) detection. You can enter either an IP address or a domain name — the system automatically resolves the IP via DNS.
The tool shows country, region, city, postal code, ISP name, organization, and autonomous system (AS) information. It also performs reverse DNS lookup (PTR record) to find the hostname associated with the IP address. You can enter either an IP address or a domain name — the system resolves it automatically.
Common use cases: identifying visitor locations for geo-targeting, checking VPN/proxy detection, verifying CDN node locations, and investigating suspicious traffic sources. For domain-related lookups, combine with WHOIS and DNS lookup. Our database is updated weekly from MaxMind GeoLite2.
Country accuracy is 95-99%. City is determined with 50-80% accuracy and may deviate by tens of kilometers. An exact address cannot be determined by IP — only an approximate area.
An AS is a group of IP networks under single management (usually an ISP or large organization). Each AS has a unique number (ASN). AS information helps identify the hosting provider and network infrastructure.
Reverse DNS (PTR record) maps an IP address back to a domain name. Used to verify mail server legitimacy, host identification, and diagnostics. Not all IPs have PTR records.
No, IP geolocation cannot determine an exact physical address. It shows an approximate city or area. For precise location, GPS or Wi-Fi positioning data is needed.
IPv4 uses 32-bit addresses (4.3 billion addresses, exhausted). IPv6 uses 128-bit addresses (virtually unlimited). IPv6 also improves routing and security. The transition is happening gradually.
VPN/proxy indicators: IP belongs to a data center (not ISP), open proxy ports (1080, 8080), timezone and geolocation mismatch, multiple users on the same IP. Specialized databases flag such IPs.
