IP Address Lookup
IP Address Lookup is a free online geolocation tool. It shows your public IP automatically when the page loads, and lets you look up any IP address or domain. Results are cross-checked against multiple authoritative databases — ip2region, CZDB, and IPIP — with city-level accuracy.
The tool is free and requires no registration; lookups are performed on the server against the IP databases. Useful for troubleshooting network issues, verifying that a proxy or VPN is active, tracing log entries, or checking where a suspicious IP is registered.
How to Use
- Open the page to see your public IP and its location automatically
- Enter any IP address or domain in the input box

- Compare the locations returned by the different data sources
FAQ
Is the IP lookup free?
Yes, it is completely free with no sign-up and unlimited lookups.
Why do the data sources disagree?
Each IP database collects and updates its data differently, so results can vary. That is exactly why this tool shows several sources side by side — cross-referencing them gives a more reliable answer.
Can I look up a domain directly?
Yes. Enter a domain and the tool resolves it to an IP address first, then looks up that IP's location.
How accurate is IP geolocation?
Typically down to the city level, sometimes with ISP information. IP geolocation is based on network allocation data and cannot pinpoint streets or addresses — treat it as an estimate.
