IP Address Lookup

What Is IP Address Lookup?

An IP address lookup (also called IP geolocation) determines the geographic location, Internet Service Provider, and organization associated with a public IP address. Every device connected to the internet has an IP address, and this address can be mapped to an approximate physical location using geolocation databases. Our free IP lookup tool shows you the country, city, ISP, timezone, and map location for any IPv4 or IPv6 address — instantly, with no signup required.

How to Use This IP Lookup Tool

Enter any public IPv4 or IPv6 address in the input field (or click "Use My IP" to look up your own). Click "Lookup" or press Enter to retrieve the geolocation data. View the results — country, region, city, postal code, timezone, latitude, longitude, ISP name, organization, and AS number. An interactive map shows the approximate physical location. Click any copy icon to copy a specific field.

Key Features

• Comprehensive data — country, city, region, postal code, timezone, ISP, organization, and AS number
• Interactive map — Leaflet map showing the approximate location with zoom controls
• IPv4 and IPv6 support — look up both address types
• Use My IP button — instantly look up your own public IP address
• One-click copy — copy any individual field or all results at once
• Lookup history — recent lookups stored locally for quick re-access

How IP Geolocation Works

IP geolocation works by mapping IP address ranges to geographic locations using databases maintained by geolocation providers. Internet Service Providers are assigned blocks of IP addresses, and these blocks are registered with regional internet registries that include location data. Geolocation databases aggregate this information, often supplemented by network measurement data, to provide city-level accuracy for most IP addresses. The accuracy is typically 80% for city-level and over 99% for country-level. Mobile IPs and VPN/proxy IPs tend to be less accurate because they may route through servers in different locations.

Common Use Cases

• Developers — tracing the origin of API requests and debugging geolocation-based features
• System administrators — investigating suspicious login attempts and attributing attack traffic
• Security analysts — analyzing the geographic distribution of incoming threats
• Digital marketers — verifying that ad traffic comes from the targeted geographic regions
• Network engineers — confirming CDN edge node locations and DNS resolver positions

Tips and Best Practices

Remember that IP geolocation shows an approximate location based on ISP registration data, not the exact physical location of the device. VPN users will show the location of the VPN server, not their actual location. For more precise location data, use the browser's Geolocation API (which requires user permission). When investigating suspicious activity, combine IP lookup with reverse DNS and WHOIS data for a more complete picture. The tool stores your last 10 lookups in browser local storage for convenience — clear this history using the clear button if you are on a shared device.
