NordVPN has implemented IPv6 leak protection
IP addresses are not infinite, and the majority of the most popular IPv4 IP addresses currently are exhausted in clusters. As such, IPv6, the next generation of the Internet Protocol was introduced to replace IP version 4, allowing more users and devices to create more complex IP addresses.
Although the majority of Internet users use the IPv4 Internet protocol, a few Internet providers have started offering IPv6 support as well. As such, many VPN service providers face the challenge of ensuring that a person with IPv6 is informed that their protocol may not be compatible with a VPN service that primarily supports IPv4 servers, switching from one to the other seamlessly. NordVPN is proud to say that all platforms currently supported by NordVPN have IPv6 leak protection.
In short, if a NordVPN client has an IPv6 IP address, its IPv6 interface will be blocked and only IPv4 traffic will be forwarded and encrypted with NordVPN, ensuring that your real IP address is never leaked.
Technically speaking, when establishing an OpenVPN connection, our clients add additional paths. IPv6 traffic is effectively redirected to a “black hole” inside the device. This feature occurs by default in all NordVPN applications that use OpenVPN, and does not require any user action. IKEv2 / IPsec does this automatically. Next, we plan to address IPv6 support on our servers – follow our blog for updates on this topic.
