This is being led by the Internet Society (ISOC). more information is posted on their World IPv6 Day page. World IPv6 day, scheduled for 8 June 2011, is a global-scale test flight of IPv6 sponsored by the Internet Society. On World IPv6 Day, major web companies and other industry players will come together to enable IPv6 on their main websites for 24 hours. The goal is to motivate organizations across the industry -- Internet service providers, hardware makers, operating system vendors and web companies -- to prepare their services for IPv6 to ensure a successful transition as IPv4 address space runs out. Click here to see the start time in your local area. Why is World IPv6 Day necessary? The address space used by the current version of the Internet protocol, IPv4, is expected to run out in 2011. Without action, we risk increased costs and limited functionality online for Internet users everywhere. The only long-term solution to this problem is adoption of IPv6, which provides over 4 billion times more space. IPv6 is used extensively in many large networks, but it has never been enabled at a global scale. World IPv6 Day will help industry players work together to support the new protocol on an accelerated timeline. With major web companies committing to enable IPv6 on their main websites, there are strong incentives for other industry players to ensure their systems are prepared for the transition.
