That is exactly the assumption and has been for 20 years. Nothing that works over IPv4 is broken. Just don't expect new stuff over IPv4. Don't expect new material on VHS casettes, either. Same issue.
This is exactly what my ISP has been planning for years. They figure they have a large enough class B that they do not need to even think about IPv6. In fact, when we signed up in 2011, they knew about IPv6 and told me that they will not support it. I figure it is going to take digis/JAB wireless to be losing at least 50% of their customers before they pull their head out of the sand. Every so often, I go to see if they applied for a IPv6 range yet and no they have not.
AS is AS23205, but it seems that maybe this is no longer true with the addition of AS17306. Maybe hell really did freeze over.
