Check if IPv4 and IPv6 work from this browser
An IPv6-capable ISP and router can still leave a particular device or website with an IPv6 problem. This tool checks browser access to protocol-specific web resources; it does not inspect your router, prove every destination works or certify DNSSEC.
Run an IPv4 / IPv6 connection check
Click below to load two small HTTPS resources from Google's IPv4-specific and IPv6-specific hosts. Google receives the normal web request, including your public IP. No test result is saved to LinkSpeed.
IPv4-only destination
Not tested
Shows whether the browser can load an IPv4-specific resource.
IPv6-only destination
Not tested
Shows whether the browser can load an IPv6-specific resource.
What to do if an IPv6 check fails
Compare another browser and device, restart your router if appropriate, check whether your ISP provides IPv6, and verify router firmware/settings before disabling IPv6. A successful IPv6 resource load suggests a working route for that specific destination, not universal IPv6 connectivity.
For your currently observed public IP version, use What Is My IP?. For cases where sites load inconsistently, follow websites not loading troubleshooting.
Privacy: the two resource checks contact Google directly after you click Run; LinkSpeed does not store their results. Consult LinkSpeed's privacy policy and Google's privacy notice for further information.
