Frequently Asked Questions

Are network lookups real-time?

Yes, IP lookups, DNS queries, and HTTP tests perform live network requests to provide current data.

Is my IP address logged?

The IP Lookup tool queries public geolocation APIs. We do not store your IP address or lookup history.

Why do geolocation results differ between providers?

Each provider maintains its own IP-to-location database with different update cycles and coverage. Treat any single result as an approximation, not an exact address.

Do the results reflect me if I use a proxy or VPN?

No. Results show the egress IP of the proxy or VPN you are connected through. Disconnect it if you need your real public IP.
