IPv4 / IPv6 Checker
Check whether IPv4 and IPv6 connectivity work.
IPv4 / IPv6 Checker probes IPv4-only and IPv6-only endpoints to see which protocols your browser can use, and shows the public address returned for each.
Frequently Asked Questions
Why does IPv6 fail?
Many networks still lack IPv6. A failure usually means your ISP or network path has no IPv6 route.
Which service is used?
api4.ipify.org and api6.ipify.org.
Does ToolWorld see my IP?
No. Your browser talks to ipify directly.
