If you're using a VPN on Windows 11, a DNS leak can expose your browsing activity to your ISP, defeating the purpose of a VPN. Fortunately, fixing it is easier than you think. In this guide, we'll walk you through three simple solutions to stop DNS leaks on Windows 11, ensuring your online privacy stays intact. And if you're looking for a reliable VPN that doesn't leak, consider our premium VPN service—just $1 for 30 days across all our apps.

What Is a DNS Leak and Why Should You Care?

When you connect to a VPN, your device should use the VPN's DNS servers to resolve domain names. A DNS leak happens when your system sends DNS queries outside the encrypted VPN tunnel, typically to your ISP's DNS servers. This means your ISP can see which websites you visit, even if your traffic is encrypted.

On Windows 11, DNS leaks can occur due to misconfigured network settings, IPv6 issues, or interference from certain apps. The consequences are serious: your browsing history is exposed, and your privacy is compromised.

Fortunately, you can fix DNS leaks quickly with a few tweaks.

Solution 1: Use Your VPN's Built-in DNS Leak Protection

Most reputable VPN apps include a built-in DNS leak protection feature. For example, our VPN apps—MD Proxy VPN, Nur Tunnel VPN, Ultra Tunnel VPN, and Marvs Go VPN—all have this feature enabled by default. However, sometimes it can be turned off accidentally or not work properly due to system settings.

Open your VPN app and navigate to the settings or preferences.
Look for a toggle or checkbox labeled "DNS leak protection" or "Use VPN DNS servers."
Ensure it is enabled.
If the option is already on, turn it off, then on again to reset the setting.

If you're not using a VPN that offers this, consider upgrading to a reliable one. Our premium VPN is available for just $1 for 30 days, and you can use it on all four apps.

Solution 2: Change Your DNS Settings Manually on Windows 11

If your VPN doesn't provide DNS leak protection, you can manually set your DNS servers to secure ones like Cloudflare (1.1.1.1) or Google (8.8.8.8). This ensures that even if a leak occurs, your DNS queries go to a trusted third-party resolver, not your ISP.

Right-click the network icon in the system tray and select "Network & Internet settings."
Click on "Advanced network settings" and then "More network adapter options."
Right-click your active network adapter (e.g., Ethernet or Wi-Fi) and select "Properties."
Select "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties."
Choose "Use the following DNS server addresses" and enter:
- Preferred DNS: 1.1.1.1
- Alternate DNS: 1.0.0.1
Click OK and restart your network connection.

This method works even when the VPN is not connected, but for maximum privacy, it's best to combine it with a VPN that uses its own DNS.

Solution 3: Disable IPv6 to Prevent DNS Leaks

Windows 11 often prefers IPv6, but many VPNs do not fully support IPv6 traffic. This can lead to DNS leaks because IPv6 DNS queries bypass the VPN tunnel. Disabling IPv6 is a simple and effective fix.

Open the Control Panel and go to "Network and Sharing Center."
Click on "Change adapter settings."
Right-click your active network adapter and select "Properties."
Uncheck "Internet Protocol Version 6 (TCP/IPv6)."
Click OK and restart your computer.

After disabling IPv6, your VPN will handle all DNS queries over IPv4, eliminating this common leak source.

How to Test for DNS Leaks on Windows 11

After applying any of the solutions above, you should verify that your DNS is no longer leaking. Here's how:

Visit a DNS leak test website like dnsleaktest.com or ipleak.net.
Ensure your VPN is connected.
Run the test. It will show which DNS servers are being used.
If you see only your VPN's DNS servers (or the ones you manually set), you're safe.
If you see your ISP's servers, the leak persists, and you may need to try another solution or contact your VPN provider.

Regular testing is a good habit, especially after Windows updates or network changes.
