"The point about Geofeed (RFC 8805) manipulation is the most overlooked part of this. We’ve moved from an era where an IP’s location was determined by physical infrastructure to an era where it’s determined by whoever manages the CSV file.

The 'house of cards' exists because there’s a massive gap between registration (who owns the block) and routing/reputation (how the block is used). As long as reputation databases trust self-published geofeeds over verified RIR registry data, the incentive to 'launder' data center IPs into residential proxies will be too profitable to ignore. The only way to break the cycle isn't just to 'stop hoarding,' but to demand tighter verification between the actual network owner and the published Geofeed data."

Highly unlikely we will ever see the day IPv4 is not used at all. There are too many legacy systems in place, so dual stack will always be required. The value of IPv4 may drop as it related to the price people pay, however, it will play a key role for decades to come.

As for the government mandate, also not possible. It would take our major ISPs over a decade to make this work, and the lobbyist would never allow it.

With that said, the DOD did make an interesting decision to move 175 Million IPs recently in routing tables.

In fact, all the large ISPs and hosting providers are stocking up on IPv4 and buying them at places like ipv4connect.com...

doubt we will ever get rid of IPv4 altogether. Dual stack will probably always have a need for backwards compatibility.

It's tough because of backwards compatibility issues.
