    What Is an IPv6 Address?

    IPv6 is the newer version of the Internet Protocol, designed to replace IPv4 as its address space runs out. IPv6 addresses are longer (e.g., 2001:0db8::7334) and can support virtually unlimited devices. Many ISPs now assign IPv6 by default.

    Unlike IPv4, IPv6 addresses are often assigned directly to individual devices rather than shared across a network. This makes them more precise — but also more revealing from a privacy standpoint. You can check both addresses using our IP address tool.

    What This IPv6 Checker Shows

    • Your IPv6 address (if available)

    IPv6 Leak Test

    If you're using a VPN, your IPv6 address may still be visible even if your IPv4 is hidden. This is called an IPv6 leak.

    If you see your real IPv6 address above while connected to a VPN, your connection is leaking. To fix this, disable IPv6 in your device settings or use a VPN that supports IPv6 tunneling.

    Why Checking Your IPv6 Address Matters

    Testing your IPv6 status helps you verify your privacy setup and catch potential leaks before they expose you. Many VPNs only handle IPv4, which means your real IPv6 address could reveal your actual location.

    Privacy Note

    IPv6 addresses can be more persistent and device-specific than IPv4, making them potentially easier to track. This tool shows what's visible to websites. We don't store, track, or log any of your data.

    Frequently Asked Questions

    Is this IPv6 leak test free to use?

    Yes, our IPv6 leak test is 100% free and ad-free. We believe privacy diagnostics should be accessible without intrusive tracking or advertisements.

    Why don't I see an IPv6 address?

    Your ISP, device, or network may not support IPv6 yet. You could also be behind a router or firewall that only allows IPv4 traffic. Many older home routers disable IPv6 by default.

    What if I only see an IPv4 address?

    It means IPv6 isn't available or active on your current connection. This is still common — many ISPs haven't fully rolled out IPv6 support. Your browsing will work normally on IPv4 alone.

    Can I get an IPv6 address with a VPN?

    Some VPNs support IPv6 tunneling, while others block IPv6 entirely to prevent leaks. If your VPN doesn't handle IPv6, your real IPv6 address could be exposed even while the VPN is active. Check your provider's documentation.

    Is IPv6 more secure than IPv4?

    IPv6 includes IPSec as a built-in feature, which provides encryption and authentication at the network layer. However, it doesn't replace the need for firewalls, HTTPS, and other security measures. IPv6 can also make devices easier to track due to persistent addresses.

    What is my IPv6 address used for?

    Your IPv6 address identifies your device on the internet, similar to IPv4. Websites, apps, and services use it to route traffic to and from your device. Because IPv6 addresses are often unique per device, they can also be used for tracking.

    How do I enable IPv6 on my connection?

    IPv6 must be supported by both your ISP and your router. Check your router settings for an IPv6 option and ensure it's enabled. If your ISP doesn't offer IPv6, you may be able to use a tunnel broker service as a workaround.
