IPv4 / IPv6 CHECKER

Know which internet protocols your connection can reach.

Test IPv4 and IPv6 independently, view the public address used by each protocol, and identify your browser's preferred route.

Checks run from this browser. A failed probe can reflect network conditions, browser restrictions or an unavailable service; it does not prove that a protocol is unsupported.

Run the check to test IPv4 and IPv6 availability from this browser.

WHAT THIS CHECK MEANS

Independent tests

IPv4 and IPv6 are contacted through protocol-specific endpoints, so each result can succeed or fail independently.

Public addresses

The displayed address is the public IP seen by the test endpoint, not a private address used inside your network.

IPv6 readiness

A working IPv6 result indicates that this browser can reach IPv6-only internet services directly.
