VPN providers are focused on privacy and security. They protect against IPv6 leaks. Although the internet is moving slowly towards this new protocol, not many VPNs support it. Only a handful of VPN providers support IPv6.

What’s IPv6?

Nobody could have imagined that the Internet would be a global communications network when it was first created. At that time, there were just a handful of devices connected to the Internet. Each device was assigned an IP address.

The internet is connected to 8 billion devices today. It is impossible to identify every device with the IPv4 addresses, so IPv6 was created.

IPv6 is an improved version of the 32-bit IPv4 predecessor. It is an IP protocol of 128 bits length that can hold up to 3.4×1038 unique address. This number is sufficient to assign an address to each device. The transition to the new version can be slow and costly because of its lack of backward compatibility.

Why don’t VPN providers support IPv6

You can get both IP addresses from ISPs. Many VPN providers don’t support IPv6 for technical and economic reasons. They chose to block it.

It’s relatively simple to set up a dual-stack host. It is difficult to overcome technological problems in security. You must address DNS and IP leakage issues in order to make IPv6 work.

When privacy is at stake, it’s important to handle corner cases, such as when switching servers are necessary. Your traffic could be exposed even if you disconnect from VPN for a few seconds.

It’s economically more profitable to support IPv6 than block it. The internet runs mainly on older versions of IPv6 so spending resources to support them seems inefficient. VPN companies prioritize marketing over tackling technical challenges. It’s not worth the effort and it isn’t needed by many people.

VPN over IPv6 Network

Why does VPN not work with IPv6 It doesn’t support it. It is unfortunate that some popular US mobile networks, such as T-Mobile, are IPv6-only. A VPN that does not support dual stacks on such networks will not work.

Some websites and hosting providers only work with the latest IP version. There aren’t many websites that work on both IP versions, so there are not many. They can only be accessed via VPN that supports IPv6.

How can you prevent IPv6 VPN breakout

VPNs that don’t support IPv6 often block your OS’s entire protocol stack. This happens automatically when you connect to VPNs.

NordVPN, for example, is a popular service which does not allow IPv6 traffic. After connecting, it simply changes the address value to .. This local network address is not permitted to be routed publically and cannot be leaked.

Providers that support IPv6 are in a different position. Many technical issues must be considered when setting up the network. You should, for example, not leak your IP address when connecting to another server.

DNS queries should also be addressed. VPN apps that are not properly configured can leak DNS requests and bypass VPN tunnels.

You need a VPN service that can handle all scenarios to prevent IPv6 leaks. To protect against IP leaks, an internet kill switch is a must-have.

There’s an easy way to check IP leaks in case you are concerned about your online traffic being exposed.

How do you test IPv6 leaks

It doesn’t matter if your VPN supports IPv6. You need to test for IP leaks. You can check the ipleak.net site to find out how to do this. Here are some ways to test for VPN IPv6 leaks.

  1. Connect to a VPN server
  2. Visit IPleak.net website
  3. Wait until all automated tests pass
  4. You can check the results for DNS and IP leakage

A VPN that is not compatible with IPv6 should produce an unreachable result. The result should differ if a VPN supports such traffic. Both your IP addresses before and after connecting to the VPN server should be totally different.

Wireshark is a more advanced method of testing, but it requires advanced networking knowledge and scripting.


Mnay VPNs don’t support the latest version of IP protocol, but instead block it. Due to technical difficulties, it is difficult to create a dual stack that is great. Perfect Privacy works with IPv6. It is the best.
