IPv6 Test

This IPv6 test checks whether your browser can use IPv6 and shows your IPv6 address when one is detected.

If IPv6 is not detected, your internet connection may still work normally over IPv4. Router settings, ISP support, VPN mode, DNS rules, and browser policies can all affect IPv6 availability.

What the IPv6 result means

A successful result means this browser reached the test endpoint over IPv6 and a public IPv6 address was visible for that connection. It does not confirm that every application, website, or device on the same network can use IPv6.

Why IPv6 may not be detected

• Your ISP or mobile carrier may provide IPv4 only.
• The router may have IPv6 disabled or may not receive a prefix.
• A VPN, proxy, corporate gateway, or privacy service may route only IPv4.
• The network may support IPv6 but block the specific test request.

Run the test again after changing networks or VPN settings. The displayed address may be temporary and should not be treated as a permanent device identifier.
