Virtual Private Network (VPN) is a tool that focuses on providing its clients secured and private online connection. With tight competition in the VPN industry, VPN service providers try to improve their performance, services and the most important factor, security and privacy features. This includes updating and upgrading new protocols. Some protocols protect subscribers from IP leaks and IPv6.
What is IPv6?
Back in the days when the Internet has been launched to the world, no one was able to predict that it will become a source of global communications. During those times, only few devices were able to connect and had unique IP address.
Today, with the network continuously growing there are about 8 billion devices that are connected to the internet. IPv4 addresses were not sufficient to identify each device which is why IPv6 has been created.
An upgraded version of 32-bit IPv4, the IPv6 is a 128-bit length IP protocol that could have up to a maximum of 3.4*1038 unique addresses. This means that it is sufficient enough to be able to assign unique address to each and every device.
Why do VPN providers not support IPv6?
Several Internet Service Providers (ISP) could provide two versions of IP addresses but, many VPN service providers do not support IPv6 due to economic and technical reasons. Hence, what VPNs usually do is to block it. To handle technological difficulties on security issues could be very challenging and to make IPv6 work, you will also need to work and handle IP and DNS leaks.
VPN on IPv6 Network
Why is VPN not working with IPv6? The reason is because VPNs do not support it. Hence, if you are using popular mobile networks in the US which usually are IPv6, you will not be able to use VPN on it. Fortunately, there are some sites and hosting providers that would only work on newer IP version. Luckily there are not many of them.
Best VPN that support IPv6
1. Perfect Privacy
Perfect Privacy is one of the best VPN options that works with IPv6. It comes with dual-stack servers in about 26 countries. Their security feature services include OpenVPN, SSH2 protocols, IPSec and kill switch. It also could protect its clients from DNS and IP leaks. In addition to that, it
also allows its users to have multi-hop connections plus double encryption. Perfect Privacy also offers a stealthVPN option and has the ability to hide from DPI detection.
This VPN service provider could block malware, advertisements and trackers through its TrackStop feature.
AirVPN allows IPv6 traffic. Its features are developed through OpenSource code. They have dual-stack servers which allows its clients to torrent and support most VPN protocols. Aside from that, it could also protect your connection from IP and DNS leaks. This VPN service provider is very transparent to its clients as you could inspect its technical specs and stats on their website. They allow up to 5 devices connected simultaneously.
AzireVPN supports IPv6 fully. This VPN service provider has a professional team that is highly experienced with cybersecurity. They do not store any logs not do they run RAM-disk servers. All of their servers are self-managed and they provide amazing speed. As for their security features, AzireVPN works with WireGuard. They come with model protocols and they support OpenVPN and SOCKS5.
Through this VPN you will be able to torrent and they also offer a 7-day money back guarantee.
How to prevent IPv6 breakout?
VPNs that do not support IPv6 usually block the protocol in your operating system. This is often done whenever you connect to a VPN. An example of this is NordVPN. NordVPN is one of the VPNs that does not allow IPv6 traffic. Hence what NordVPN does is setting your address value to fd00::1. This act will not allow your address to be routed publicly. Hence, it will not be able to leak. Another way is to ensure your real IP address will not be leaked. DNS queries must be taken cared too as well. If your VPN is configured incorrectly DNS could and might bypass VPN tunnels.
To be able to prevent IPv6 breakout, you will need a VPN that could handle all the scenarios as mentioned earlier.
How to test IPv6 leaks?
Testing IPv6 is very important and there are ways to do this and one way is through the site of ipleak.net. To test IPv6 leaks, all you have to do is:
- Connect to a VPN server
- Go to iPleak.net
- Wait until all the tests pass
- Check for the results and see if there are IP and/or DNS leaks.
There is another advanced way or method to test your IPv6 leaks and that is through a software called Wireshark. But, take note that you will need extensive network and scripting knowledge.
There are only a few VPN service providers that support the new IP protocol, IPv6. Most VPNs only blocks it due to economic and technical reasons. Hence it it difficult to get one that would provide a great dual stack. With that said, we highly recommend Perfect Privacy which is the perfect VPN that works with IPv6.
