Leak tests

A VPN leak check is a few separate tests, not one page. The WebRTC leak test looks for a local or public IP the browser is handing out. The torrent page is a checklist to run before you torrent; it never sees your torrent client. The DNS page only checks that the browser can reach the Cloudflare and Google DNS-over-HTTPS resolvers. It cannot see which resolver your system uses, so it is not a DNS leak test. The privacy checkup and the VPN and proxy check sit with these.

The address those checks compare against is on the IP lookup page (country, ASN, ISP, reverse DNS, and blacklist). The block that address belongs to is on the subnet calculator and the CIDR calculator.

The other groups are IP lookup and geolocation, network diagnostics, and email and domain security.
