The 6th of June 2012 is an interesting day, World IPv6 Launch Day. On this day a swathe of influential web-sites will be enabling IPv6 addresses for their services by default and not turning them off. Why is this interesting? For the most part it is not! For most people nothing should happen, things should continue working probably using IPv4, fine. For those of us with working IPv6 again nothing will change other than we will be producing more IPv6 traffic, great. It is those who have unused broken IPv6 who will start having fun, they will likely lose connectivity to the participating sites until they sort out their issues.
So why is this a good thing? This is a key step towards IPv6 adoption, and we really do not have any other choice but to adopt IPv6. Adoption will only be driven by need, and this move creates exactly that need. Such ISP and client issues need to be identified and solved, before the end users lose connectivity to even greater swathes of The Internet, those parts which only will exist on The IPv6 Internet.
