I've become a big fan of IPv6 in the last months so I was anxious to get my DSL link at home to support IPv6.

There is actually a great site out there which offers an overview of providers sorted by country which provide native IPv6:

For my part, living in Austria, will try to get connectivity from hotze.com and then dump Inode/UPC since they still have no intention of providing IPv6 in the next few years (according to their support services).
