Overview
VirtualShield offers IPv6 Leak Protection by disabling all IPv6 traffic while connected to our VPN, thus providing you with a guarantee that no Internet traffic leaks out over your regular connection while the VPN is active.
Windows
If you are using an IPv6 address to connect to the internet, we recommend enabling this option. This helps protect your system by preventing any data from leaking across your regular network without your knowledge or consent.
If you are unsure, you can use this Google link to verify if your network is using IPv6 or not.
IPv6 Protection
How to disable IPv6 traffic on your Windows computer:
Open VirtualShield and log in to your account, if you are not logged in already.
For more help logging in and connecting, see our support article.
In the Secure VPN section, click 
More and choose VPN Settings from the menu.
You can also right-click the shield icon next to your clock, then navigate to VPN > VPN Settings from the menu.
Toggle the IPv6 Leak Protection option on or off, then click the 
back arrow to return to the Home screen.
You may need to re-connect to the VPN after saving your settings before the changes will be applied.
macOS
Mac works a little bit differently. Your IPv6 traffic will be disabled automatically when the VPN is active. You can also disable IPv6 manually from your System Preferences. However, this will also impact your regular connection when the VPN is inactive.
If you are unsure, you can use this Google link to verify if your network is using IPv6 or not.

How to disable IPv6 traffic on your Mac computer:
From the 
Apple menu near the corner of your screen, select System Preferences.
If you don't see the System Preferences option, select System Settings.
In the System Preferences window, click Network.
Select your network connection on the left-hand side (usually Ethernet or Wi-Fi), then click the Advanced button.
Select the TCP/IP tab. Next to Configure IPv6, set it to Off or Link-local Only.
Click OK to save your changes.
If you connect to a different network, we recommend repeating this process with the new network.
Common Questions
Do I need to disable this option if I'm not using IPv6?
No, your regular (IPv4) address will still be fully protected. However, we recommend enabling this option in case your network changes, or your Internet Provider offers IPv6 in the future.
Why can't I see this option on my device?
On most devices our app will disable IPv6 traffic automatically when the VPN is active. Depending on the device you're using, you may need to disable it manually.
