I am not aware of the reason they went to such a high-complexity setup. They could have simply added a 4 or 6 digit hex code prefix to the IP addresses and figured a way to geographically lock that code. Sure, that wouldn't give you the 340 trillion trillion trillion IPv6 addresses, but it would have turned 4,294,967,296 IPv4 addresses into 281,474,976,710,656 ipv? addresses and been easy enough to remember that on your local "block" you use idk, "AF09" as the prefix or whatever, and every person on the planet would have about 35 ip addresses (or ~9,000 with a 6 digit prefix) available to them on the new setup not even accounting for NAT
