250 million-plus reserved IPv4 addresses could be released – but the internet isn’t built to use them

Yes but you only have 8 bits of subnetting so most of that address space isn't useful. In another brilliant move by the IPv6 team, the entire last /64 of the address space is not routable. The reason they did this is so that the MAC address of every device could be in that part but smarter people quickly realized that was a really, really stupid idea. Like so many other things in IPv6 that are still being reworked, broken, respecified, and redisgned. Not to mention that it's completely incompatible with IPv4 despite IPv4 having a "version" field. As these core original design flaws pile up it turns out IPv6 is just a really bad design that nobody wants. Everybody wants more address space, IPv6 is not the way.
