Disabling IPv6 on Windows

IPv6 is a new internet protocol that may cause VPN leaking issues if your VPN server can’t handle requests routed through it. Short of changing VPN providers, you can fix an IPv6 leak by disabling the protocol’s usage on your device.

Here’s how you do so on Windows 10.

NOTE that unless it’s the source of a VPN leak, disabling IPv6 is generally not a good idea. Do this as a last resort, and make sure you understand the options before playing around with them!

 

STEP 1. FInd the Network or WiFi icon in your device’s System Tray. Right-click it, and click Network & Internet Settings.

STEP 2.  In the settings window, select Change Adapter Options.

STEP 3.  In the next screen, you will see a list of all your adapters. Only one of it is currently being used to connect to the Internet — the one without a red X. Right-click on that adapter, then click Properties.

Note that you may have to enter your administrator password here, if you’re not logged in as the device admin.

STEP 4. The Properties tab of your adapter will show. Among the things you will see will be a list of protocols in use, marked with checks. Find the list item called Internet Protocol Version 6 (TCP/IPv6). Uncheck its box, then click OK.

STEP 5. Restart your computer, then run the IPv6 leak test again. This time you should no longer have a leak!

Remember, ensuring you don’t have a VPN leak is just one of the many things you can do to make sure your VPN protects your privacy as it’s supposed to. You can also check out our list here of the things you can do to upgrade your browsing habits to ensure your anonymity!
