How about we just declare IPv4 addresses to be static as of ..yesterday. They are not unique of course, but at some level they are. Done. Solve a whole bunch of heart ache.
That's why your ISP doesn't do statics for free anymore
Check the charts for price since 2020. It looks like IPv4-block prices almost tripled 2020-2021. Then seem to have been in gradual decline since then. I'm rather surprised.
Your ISP doesn't do statics, but not because of the cost.
Since then prices have come down. I can only speculate that high prices caused a bunch of organisations to decide to sell their unused IP blocks. I suppose the question is: Does the market now have enough spare capacity to see us through to IPv6-only adoption at reasonable IP costs, or will we be seeing high prices again in 5+ years?
Of course prices have collapsed since then, and in real terms are back or below 2019 levels
As prices go up, previously impractical sources will satisfy demand just enough.
In other words, I think we’ll be stuck in IPv4 price limbo for a very long time.
It is core of problem with IPv6 adoption - from ISP perspective it do not solve any problem because they still needs solution for connecting to IPv4. Opposite way it works - if you have IPv4 there are bridges to IPv6.
There is no way to go from IPv4 to IPv6.
It's not great, but for 99% of consumers, they can't tell the difference. The ISP only needs a small 28 or 29 allocation, and with that they serve tens to hundreds of thousands of clients.
