- There is a lot in IPv6 that is different from IPv4. Ignoring if those changes are good or bad, it does make the transition harder.
- IPv6 was promoted way before there was demand. To some extent it is good to prepare people (and vendors). But it does create the impression that IPv6 is a failure
- Demand for IPv6 is highly asymmetrical. The party that is out of IPv4 addresses needs IPv6. But everyone who has enough IPv4 space has no reason to care.
When IPv6 was first promoted, there basically was no IPv4 market. You would just go and get more IPv4 space when needed. For the last couple of years we now have a mature market for IPv4 addresses.
It is possible to buy IPv4 addresses, but prices go up. At some point it becomes interesting to try to move traffic to IPv6.
