Most home and businesses will to use the private non-routable IPv4 addresses for a quite awhile for inside networks and most home uses have no need for a public IP address except what gets assigned to their public interface of the router/modem etc.
I’m surprised Cloud companies like AWS haven’t started charging larger more sophisticated companies for public IP addresses before now
Amazon bought half of the 18. space from MIT in 2017. I remember having to change IPs on servers. The price was a significant amount. Amazon is finally getting around to monetizing this scarce resource. Go capitalism.
