The more ISPs migrate to IPv6 and CG-NAT, the more free IPv4 addresses for everyone else. Wich means the migration will take a really long time. Also the only way to reach an IPv6 target from a IPv4 source is through a CG-NAT, so dual stack IPv6+CG-NAT deployments should be the norm for many years to come.

> dual stack IPv6+CG-NAT deployments should be the norm for many years to come One can hope. I wouldn’t be too surprised if some ISPs try to deploy just CG-NAT and punt on IPv6 deployment as long as they can.

  Supporting IPv6 natively would be cheaper as they'd need to invest less in NAT capacity.

    They will more than make up the difference by increasing the rent for the public IPv4 addresses they got when they were still available.

      Yeah, but it's not like offering IPv6 prevents those rents, so why waste that money on NAT capacity if they can pocket it instead?

        Once IPv6 is available widely enough, prices for IPv4 addresses will plummet because there is a nearly unlimited amount of IPv6 addresses available for much cheaper or free

> The more ISPs migrate to IPv6 and CG-NAT, the more free IPv4 addresses for everyone else. Uhhh, they're not returning their IPv4 addresses to any kind of free pool. Those IPs that they have allocated remain with them.

  If they can make money selling them I don’t see that happening.

    Current cost of an IPv4 address: $20 Value of product that can be sold per IP address: $5 - $1000/month. Having worked in an organisation that had millions of addresses, we opted to carry on having a long term sustainable business over selling our IPs for short term gains. Eventually the addressable market on IPv6 will reach a critical mass. At that point, the value of IPv4 will become relevant to niche markets only.
