A Snapshot of IPv6 for World IPv6 Launch Day, June 06, 2012 Celebrate World IPv6 Launch day with facts, figures, insights and more to help you plan for that inevitable IPv6 migration.
Growth in autonomous systems is one thing, but what's running on IPv6? According to Hurricane Electric, the number of IPv6 AAAA DNS records in the top-level domains is small, making up less than 1% of all domains (with the noted exception of .de in Germany). Of those AAAA records, an even smaller number of IPv6-enabled DNS glue records exist. That means that some domains have IPv6 records added, but there's no way to reach them. It's parking, of a sort.
According to Alexa, many popular sites (including Facebook, Google, Vonage and our own InformationWeek and XKCD) have IPv6 addresses. Network Computing is partially IPv6-enabled. The main site is reachable via IPv6, but the media and ad elements are still IPv4 only.
