Happy World IPv6 Day
June 8, 2011 is World IPv6 Day. Many large organizations around the world will offer their primary website’s content on the IPv6 Internet in addition to IPv4. If all goes well, the hope is that this will be a permanent change and these sites will operate dual-stack.
You can test your ability to reach the IPv6 Internet by visiting test-ipv6.com.
If you operate a website, you can make your content available directly to IPv6 users, too. Obtain a native IPv6 address block from your Internet provider, configure your servers with an IPv6 address, then add AAAA entries to your DNS for the new address.
