Comcast, Time Warner Cable, SoftLayer Technologies and Rackspace Hosting joined the ranks of Internet industry players committing to participate in World IPv6 Day, a global event coordinated by the Internet Society. The global scale 24-hour "test flight" of the next generation Internet Protocol on June 8 is intended to enable the industry to test IPv6 readiness and prepare for seamless full deployment.One of the goals of World IPv6 Day is to expose potential issues under controlled conditions and address them as soon as possible. Scheduling the event for a 24-hour period on June 8 gives participants the opportunity to ready their systems for an industry-wide "test-flight" while working together to plan for long-term deployment of IPv6."World IPv6 Day is important to further the deployment and wide spread enablement of IPv6," said John Brzozowski, chief architect for IPv6 and distinguished engineer at Comcast, in a statement. "Being able to test our infrastructure at scale and verify our customers' experience is essential to seamless enablement.""We're working hard to make IPv6 available to our customers," said Lee Howard, director of network technology for Time Warner Cable, in a statement. "All transitions have risks, and we're glad to be working together to minimize those risks with this significant test."For more information about World IPv6 Day, visit www.internetsociety.org/worldipv6day.
