What is 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.

What is IPv6 leak?

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.
