Best VPNs with IPv6 Support (only these few fully work)

VPN providers focus on security and privacy. They try to protect from any IP leaks, including IPv6. The internet is slowly moving towards the new protocol adoption, but not that many VPNs support it. There are only a few VPN providers that work with IPv6.

What is IPv6

When the Internet was created, nobody thought that it would become a global communications network. There were only a few devices connected at that time which were assigned a unique IP address.

Nowadays, the network is so big that there are around 8 billion devices connected to the internet. The number of IPv4 addresses is simply not enough to identify each device, that’s why IPv6 was created.

IPv6 is an upgraded version of its 32-bit IPv4 predecessor. It is a 128-bit length IP protocol that can have up to 3.4×1038 unique addresses. The number is more than enough to assign a unique address to every device. But the transition to the new version is slow and expensive because it lacks backward compatibility.

Why do VPN providers not support IPv6

There are already ISPs that assign you both versions of IP addresses. Yet, many VPN providers do not support IPv6 due to technical and economic reasons. Instead, they chose an easy way out – to simply block it.

It is relatively easy to create a dual-stack server. But, to tackle technological difficulties when it comes to security is challenging. To make IPv6 work you need to handle IP and DNS leaks.

Handling corner case scenarios, for example, when switching servers becomes essential for privacy. Even a few milliseconds spent disconnected from VPN could leave your traffic unprotected.

There’s an economic incentive to block rather than support IPv6 too. As the internet mainly runs on the older version, spending resources to support the new version of the protocol seems inefficient. VPN companies prioritise marketing rather than tackling hard tech challenges. There’s very little value for business and way too little people who really need that feature.

VPN on IPv6 Network

Why is VPN not working with IPv6? The answer is simple – because it does not support it. This is unfortunate because some of the popular mobile networks in the US like T-Mobile are IPv6 only.  You will not be able to use a VPN which does not have a dual stack on such a network 

There are some websites and hosting providers that also work only on the newer IP version. Luckily there aren’t that many of them and almost all websites work with both versions. Only a VPN with IPv6 support can access them.

So, which VPN supports IPv6?

Best VPNs with IPv6 Support

Perfect Privacy

Perfect Privacy is one of the best VPNs that work with IPv6. It is a privacy-focused service with dual-stack servers in 26 countries. All servers run on RAM-disk so it protects all their users’ data from being collected.

This premium VPN service has great security and OpenVPN, IPSec, and SSH2 protocols. To protect you from all leaks it has DNS and IP leak protection along with Internet Kill Switch.

It allows multi-hop connections that are double-encrypted. A StealthVPN option is also there that hides from DPI detection.

Perfect Privacy can block ads, malware, and trackers with their TrackStop feature. With its unlimited speed and bandwidth the service is great for P2P and torrenting. But, it’s not a fit if you want to unblock Netflix.

All plans come with a 7-day money-back guarantee.

  • How to prevent IPv6 VPN breakout

    VPNs that do not support IPv6 usually block the whole protocol stack in your OS. This is usually done automatically every time you connect to a VPN.

    For example, NordVPN is a popular service that currently does not allow IPv6 traffic. It simply sets the address value to fd00::1 once connected.. This is a local network address that is not allowed to be routed publicly, so can not be leaked.

    A different situation is with providers that do support IPv6. The set up must take into account many technical challenges. For example, prevent leaking your real IP address while reconnecting to another server.

    DNS queries must also be handled too. If VPN apps are incorrectly configured they can leak your DNS requests and bypass VPN tunnels.

    To prevent an IPv6 breakout you need to use a VPN service that handles all corner case scenarios. An internet kill switch is also a must-have feature to protect from IP leaks.

    If you’re worried about exposing your online traffic, there’s a simple way to test IP leaks.

    How to test IPv6 leaks

    Whether you are using a VPN that supports IPv6 or not, testing for IP leaks is important. The easiest way to do that is to check on the ipleak.net website. Here’s how you should test for VPN IPv6 leaks:

    1. Connect to a VPN server
    2. Visit IPleak.net website
    3. Wait until all automatic tests pass
    4. Check the results for IP and DNS leaks

    The expected result for a VPN that does not work with IPv6 is that the test should show unreachable. If a VPN supports such traffic the result should be different. Your both IPs before connecting to a VPN server and after should be completely different.

    An advanced way to test is to use a software called Wireshark, but that requires extensive networking knowledge and scripting.


    Mnay VPNs do not support the new version of IP protocol but rather block it. It is hard to have a great dual stack due to technical challenges. The best so far is Perfect Privacy that works with IPv6.
