Not a fixed/wireline ISP.
The "con" that consumers' game consoles, smart TVs, and IoT things won't
work is a pretty big "con." I was working with a small ISP that was
running out of IPv4 addresses, and they kept saying "NAT64." I warned
them that while NAT64 would solve their runout problem, it would drive a
lot of unhappy customer calls.
It would be interesting if someone offered a NAT64 service (maybe for a
reduced price). Buyers could tell consumer electronics companies, "I
can't use your device without IPv6." But qualifying the customer who
would do that would be more expensive, I think, than just buying IPv4
addresses. Also but, would that be a Net Neutrality problem, charging
less for a service that has arguably worse access to Amazon, Reddit,
Twitter, etc.?
