Your PC is leaking IPv6. The above address has been detected and can allow unwanted parties to see what you do on-line.

We did not detect IPv6 on your Internet connection. This means that only IPv4 traffic is available and your real location cannot be leaked through IPv6
IPv6 is a 128 bit address system of the Internet Protocol (IP) which is used to identify devices on a network. It allows for a significantly higher number of addresses or devices than the currently most deployed IPv4 revision (4, 294, 967, 296 addresses vs (40, 282, 366, 920, 938, 463, 463, 374, 607, 431, 768, 211, 456 addresses).
IPv4 will one day become history as the world slowly moves towards the newer IPv6 standard which removes all real-life scaling issues of its predecessor. Adoption of IPv6, however, has been very slow – mainly due to backward capability issues. While your PC, phone, tablet or even TV support IPv6 already, the vast majority of websites do not.
Because of the limited availability of IPv6 around the world most VPN providers fail to direct IPv6 traffic through the VPN tunnel. If your ISP supports IPv6 and you connect to an IPv6 enabled website, your browser will connect to IPv6 address outside of the VPN connection, using your ISP directly. Your real IPv6 address leaks this way.
Astrill VPN offers IPv6 Leak Protection by disabling IPv6 traffic while connected to our VPN thus providing you with a guarantee that no Internet traffic leaks out over your regular connection while connected to VPN. This feature is optional and can be disabled if required. However IPv6 leak does reduce your on-line anonymity and allows 3rd parties to track your activities. We strongly suggest you use IPv6 leak protection.
Some VPN services do not carry IPv6 traffic through their encrypted tunnel. If your ISP supports IPv6 and you visit an IPv6-enabled website, your browser may connect outside the VPN tunnel and expose your real IPv6 address.
Use a VPN with IPv6 leak protection. You can also disable IPv6 on your device or router when you do not need it, but VPN-level protection is easier to apply consistently across networks.
Open your device’s network settings or run ipconfig in Windows Command Prompt. If an IPv6 address appears for an active network adapter, your connection supports IPv6. You can confirm the result with this IPv6 leak test.
No. A VPN can operate over IPv4 without IPv6. What matters is that the VPN either carries IPv6 traffic securely or blocks it while connected so your real IPv6 address does not leak outside the tunnel.
Choose a VPN with IPv6 leak protection, keep your VPN app and device updated, and verify the connection with an IPv6 leak test. A correctly configured firewall can provide an additional layer of protection.
Yes. Websites and network operators can observe an IPv6 address that connects to them. A VPN with IPv6 leak protection helps prevent your real IPv6 address from being exposed outside the encrypted tunnel.
