I was client at "Kabel Deutschland, Germany" and they offer native IPv6 for their customers, with "Dual stack lite" as the routing option to reach the IPv4 world. It performed poorly for me, perhaps due to bad load balancing of the IPv4-gateways. I switched to a buisness plan (+10EUR/month) of the same ISP and now have an own static IPv4 adress and not even native access to IPv6 any more. This is a clear statement how they think about their IPv6 support.
