This guide will help you turn on or off DNR (Discovery of Network-designated Resolvers) in Windows 11.

What is DNR? It’s a new feature that helps your computer find and use special secure DNS servers automatically. These servers keep your internet browsing safer and more private by encrypting DNS traffic — which means your online activities are harder to spy on or tamper with.

Note: DNR is a new feature that’s only available if you are part of the Windows Insider Preview program. This program lets you try new Windows features before they’re made available to everyone.

How to Turn On DNR in Windows 11

If you’re in the Windows Insider Preview program, follow these simple steps:

1. Open the Registry Editor:
   • Press Windows + R on your keyboard.
   • Type regedit and press Enter.
   • If a message appears asking for permission, click Yes.
2. Go to this location in the Registry Editor:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters

3. Look for EnableDnr in the right pane:
   • If you see EnableDnr, double-click it.
   • Change the value to 1 to turn on DNR.
   • To turn it off, change the value to 0.
4. If EnableDnr is missing:
   • Right-click on an empty space in the right pane.
   • Choose New → DWORD (32-bit) Value.
   • Name it EnableDnr.
   • Double-click it and set its value to 1 to enable.
5. Close Registry Editor and restart your computer to apply the changes.

That’s it! Your Windows 11 device will now use encrypted DNS servers automatically, making your internet use more secure.

More About DNR

DNR automatically discovers encrypted DNS servers using new internet standards (like DNS over HTTPS or DNS over TLS). This means you don’t have to set anything up manually to get better privacy and security online.

Remember, this feature is still new and only works if you’re part of the Windows Insider Preview program. If you want to join, check out this easy guide: How to Get Windows 11 Insider Preview.
