Your IP and country/region are read by the server when you open the page; browser, screen and timezone are read locally on your device and never pass through the server.
Data comes from live resolution via Cloudflare public DNS (1.1.1.1).
Data comes from the registries' official RDAP endpoints. A few TLDs (some ccTLDs) don't publish RDAP and may return nothing — check with your registrar instead.
The server fetches the target URL for you and shows the status code, redirect chain and all response headers. Internal addresses are not supported.
