IPv6 Test

Check whether your current public IP is IPv4 or IPv6 and learn how IPv6 affects modern internet connectivity.

IPv6 is the newer internet addressing system created to support far more devices than IPv4. This test shows whether your current connection is using IPv4 or IPv6 when it reaches the website.

Knowing your IP version can help troubleshoot router settings, ISP support, VPN behavior, firewall rules, and websites that behave differently on IPv4 and IPv6 networks.

What the IPv6 test shows

The page displays your visible public IP address and whether it appears to be IPv4 or IPv6. It also shows network details when public lookup data is available.

Why IPv6 matters

IPv6 provides a much larger address space and can simplify some routing needs. Many modern ISPs, mobile carriers, and cloud providers support IPv6 alongside IPv4.

Dual-stack connections

Many networks use dual stack, which means both IPv4 and IPv6 are available. A website may prefer one version depending on DNS, browser, operating system, and network settings.

Common IPv6 troubleshooting tips

If IPv6 is expected but not visible, check router support, ISP settings, operating system configuration, firewall rules, and whether a VPN is disabling or routing IPv6 traffic.

Frequently Asked Questions

How do I know if I am using IPv6?

Run the test and check the IP Version field. IPv6 addresses contain hexadecimal characters and colons.

Can I have both IPv4 and IPv6?

Yes. Many connections support both versions and choose one depending on the website and network route.

Does IPv6 reduce privacy?

IPv6 can expose different address behavior depending on configuration, but modern systems often use temporary privacy addresses.
