This year's IPv6 World Launch Day has increased IPv6 presence on the global Internet. While usage is still low (< 1%) much of the Internet's popular content (>40%) is now accessible though IPv6. We just published the first of a series of posts on IPv6 at http://laws.qualys.com. Do you have a plan already and what are your biggest challenges with IPv6? Looking forward to hearing your thoughts and stay tuned for more resources to come.
