Wednesday June 8 2011 is World IPv6 Day and there will be plenty of representation by IIS7 on the Windows Server side. From Microsoft we will have participation in this event by Microsoft.com, Bing.com and Xbox.com; all of which run IIS7 web servers on their front end.
Using IPv6 with IIS7 is trivial and intuitive, and we have deep integration of IPv6 features into the IIS product. From creating site bindings to logging to security features like IP Restriction, IIS has full support for IPv6 including validation in our management interfaces.
