IP Address Lookup
Find geolocation and network information for any IP address
Free Online IP Lookup Tool
What is an IP Address?
An Internet Protocol (IP) address is a unique numerical label assigned to every device connected to a computer network that uses the Internet Protocol for communication. It serves two principal functions: host or network interface identification and location addressing.
How Does IP Geolocation Work?
IP geolocation maps an IP address to the real-world geographic location of an internet-connected computing or a mobile device. It relies on databases maintained by Regional Internet Registries (RIRs) and third-party providers who aggregate data from ISPs, routing tables, and other sources.
Why Use Our IP Lookup Tool?
Our free IP lookup tool provides detailed information about any public IP address. Simply enter an IPv4 or IPv6 address, and we'll retrieve its estimated physical location (city, region, country), network details (ISP, ASN), and time zone information.
Common Use Cases
- Security & Fraud Prevention: Identify suspicious login attempts or transactions originating from unexpected locations.
- Network Troubleshooting: Diagnose connectivity issues by verifying the routing and ISP details of an IP address.
- Content Localization: Understand where your users are coming from to deliver region-specific content or language options.
How accurate is IP geolocation?
Country-level results are usually correct. Region and city are estimates that can be off by tens or even hundreds of miles, especially for mobile networks, which route traffic through a few central gateways. VPNs, proxies, corporate networks and privacy relays show the location of the network exit point, not the person. Treat the result as a hint about where traffic comes from, never as a precise address.
IPv4 and IPv6
IPv4 addresses look like 203.0.113.42 and allow about 4.3 billion addresses. IPv6 addresses look like 2001:db8::1 and have a vastly larger address space. Private ranges such as 10.0.0.0/8, 192.168.0.0/16 and fc00::/7 are used inside local networks and have no public location.
Privacy
Lookups are sent from your browser directly to a third-party geolocation service (ipapi.co, with ipinfo.io as a fallback). When you look up your own address, that service sees your public IP. See our Privacy Policy for details.
