My hosting company has enrolled this site in their beta for IPv6. All I had to do was ask.
If you have a hosted site, I highly recommend that you open a ticket asking for your site to be available via IPv6. If they don't offer it, ask for an arrival date and keep them to it. Enroll in any beta tests and so on. The more demand hosting companies see, the better.
And I was just thinking about a new talk about IPv6 and decided against it because IPv6 is old an boring. ;-) I think you changed my mind. ;-)
There is still much work to be done. Very few of the big players have IPv6 running. Sad but true most of the problems with IPv6 are on Layer 8 and 9 (politics and religion). :-(
BTW: According to http://sixy.ch/ my blog is IPv6 enabled for more than 1700 days.
