alt Hacker NewsPlease consider that maybe the people working on v6 weren't actually complete imbeciles and did in fact think things through.
It is possible for the world to change, and for designs and plans and viewpoints 30+ years ago to be less correct today.
This world is not that world. That world had massive concerns about the processing cost of NAT. That was one reason for ipv6. It also had different ideas about where the net would go. We now know that the "internet of things" and "having your fridge online", as well as "5G in everything so people can't firewall it off" is just insane and malign.
We also know that tying an IP address to a person (compared to an ISP using NAT) reduces privacy. That devious and devilish actors abound.
Even though they thought these things might be neat, many of them aren't.

The processing cost of NAT is still a problem. There's that classic post by a Native American tribal ISP where it was cheaper for them to pay to replace their clients IPv4-only Roku devices with IPv6 capable Apple TVs than to upgrade their CGNAT appliance to handle the video traffic.
None of that has anything to do with what you said in the post I replied to. "Add an extra octet to v4 addresses" has hard technical barriers to deal with if you want it to work, regardless of what the world looks like or what you're designing for.

None of this is really relevant either. IP's job is to handle the addressing used when sending data over the Internet, and it should do this job well regardless of what people end up doing with it.

We don't tie IP addresses to people. PI allocations might sort of count, but regular users don't get those.
