IPv6 leak test
Your current request arrived over IPv4. The separate IPv6-only route test is temporarily unavailable. The address above describes this request; it does not independently verify a VPN tunnel.
Local tests
Find public addresses exposed by the browser.
Check whether an IPv6 path is available.
Active DNS and IPv6-only tests are temporarily unavailable. You can compare free VPN plans and run the WebRTC check.
Why it matters
A device can hold both protocols at once. If the VPN installs only IPv4 routes, an IPv6-capable destination may receive the ISP-issued IPv6 address.
If a VPN does not support IPv6, blocking external IPv6 while connected is usually safer than silently using the ordinary route. Retest after sleep and network changes.
