IPv6 connectivity test
Test whether this browser can reach an IPv6-only address service.
Can this browser use IPv6?
This contacts ipify’s separate IPv4-only and IPv6-only services. Each service receives the address used to reach it. No account or device location permission is needed.
An IPv6 result means this browser reached the IPv6 service. It does not prove that all apps use IPv6 or that your VPN covers IPv6. Compare with your VPN’s documented behavior. A missing IPv6 result is inconclusive about its cause.
