Do VPNs support IPv6?

Most VPN providers don’t support IPv6 and rely on IPv4 instead. NordVPN disables IPv6 automatically, so you don’t need to do any configuration yourself. Even if your device uses IPv6, your traffic is still protected because it is redirected through an encrypted VPN tunnel and your IP address is hidden.

With one NordVPN account, you can protect up to six different devices: tablets, smartphones, laptops, and more. You can also configure NordVPN on your router and protect all gadgets connected to your network.

NordVPN allows you to encrypt your data on all devices, from smartphones to routers. And it doesn’t matter whether they support IPv4 or IPv6.
