'In a nutshell, if a NordVPN customer were to have an IPv6 IP address, their IPv6 interface would be blocked and only IPv4 traffic would be rerouted and encrypted with NordVPN, which ensures that your real IP address never leaks.
Technically speaking, when establishing an OpenVPN connection, our clients add additional routes. IPv6 traffic is effectively rerouted to a “black hole” within the device. This feature happens by default on all NordVPN applications that use OpenVPN, requiring no user action. IKEv2/IPsec protocol does this automatically. Up next, we plan to tackle the IPv6 support on our servers – follow our blog for updates on the topic.' Tech Support more or less verified this.
So essentially here it is almost 2019 and NordVPN still doesn't support IPv6. It deselects IPv6 on your Wifi Adapter properties settings. This is on Windows 10 1809+. I just thought that people who really need IPv6 ( I don't think I currently do) that they might want to be made aware of this. Also in case that you don't know, this NordVPN also reduces my speed throughput by up to 20%. I usually test out, on wireless, at 235/11.....or in that ball park.....Its more like 200-210 now. I do not know of any other VPN products if they also have these 'features'. HTH
p.s. I forgot to add I had to completely turnoff the IPv4 and IPv6 firewalls in my Technicolor TC8717t gateway modem/router to even get a VPN connection. Luckily the Windows 10 default firewall allows connection with no rules or setup required.
NordVPN and IPv6?
Nordvpn Ipv6 Server
Feb 28, 2017 NordVPN is proud to say that all the platforms currently supported by NordVPN have an IPv6 Leak Protection. In a nutshell, if a NordVPN customer were to have an IPv6 IP address, their IPv6 interface would be blocked and only IPv4 traffic would be rerouted and encrypted with NordVPN, which ensures that your real IP address never leaks. See full list on nordvpn.com. IPv6 is increasingly common as more devices connect to the internet, from mobile phones to Smart TVs. And as more devices go online, there will be a growing demand for the universal adoption of IPv6. Right now, however, there are only a few VPNs with full IPv6 support.
