Yes, my Internet Service Provider provides all their customers with DSL or optic fibre products with native IPv6 access to the Internet with a /56 subnet out of which the router will pick a /64 subnet dynamically to pick addresses for devices (privacy extension is supported and enabled by default). Port forwarding for IPv6 is available and possible to be used easily over the router interface / firewall configuration. All of this for free.

I don't use IPv6 at the moment though and so I have disabled it in my DSL router.
