Can IPv4 reasonably be killed yet? The ISPs are still dragging their feet on IPv6. I can't browse over IPv6 at home because my ISP (Cox) hasn't been able to consistently deploy it to residential. I'll have support for a few weeks, then go 3 months without, and then repeat. It's been like this for like 4 years.
When I helped setup our new office earlier this year, I requested IPv6 support and was told that Cox just doesn't support it at all for business lines right now.
How can anyone drop support for v4 when the ISPs still don't support v6? What good is a service that can't be accessed due to ISPs being awful?
It's a chicken-and-egg problem. ISPs have very little incentive to deploy IPv6 when not enough of their customers are demanding it. Meanwhile, people don't demand IPv6 when all of their services work just fine over IPv4.
A big drive for IPv6 adoption seems to be that some ISPs are genuinely running out of addresses. They are forced to re-engineer their network stack in order to switch to CGNAT anyways, so deploying IPv6 along with it isn't too much extra work. As long as the ISP has plenty of IPv4 space remaining, their engineers are going to have a hard time selling spending time on IPv6 to management.
