What to look for

Visible IP

The IP should match your VPN route, not your normal ISP location.

WebRTC

Modern browsers often hide local candidates with mDNS. A public real IP here is a warning sign.

IPv6

If your VPN does not support IPv6 but your browser exposes IPv6, disable IPv6 or switch VPN settings.

DNS

Use the DNS page to check whether DNS resolvers match your VPN privacy setup.
