I think the great architectural challenge would be - how does one add that byte to the IP header in a non-breaking way?
There's a surprising number of people who think you could magically expand the IPv4 address space in a backwards compatible manner.

It would be great if its true! Perhaps its really there and we're all just blind to it? Unlikely, but I'm willing to be surprised.

Which starts to sound an awful lot like an IPV6 migration.

Unfortunately none of those people have explained how it could be done in enough detail that I could try it. Most walk away when pressed but a few press on telling me it is easy so shut up and do it .
The thing with phone infrastructure though is that it is centralized. So may happen in a reasonably coordinated rollout. Global internet is a lot more distributed so it would take a very long time.
The open question is, would it take longer than IP6 has? Maybe not. Part of the reason I didn't care to use it early was because of the long addresses. If we could get a five byte address written in hex it would be somewhat user friendly.

#16What a great story. The spanning tree algo is under appreciated: this allowed people who didn’t understand networking to plug networks together the way you would plug extension power cables together,* making networking simple ( or alternatively insanely broken, when people had 400 computers on a single LAN with a rat’s nest of bridges and hubs…but unlike the extension cord case, nothing would catch literal fire). * d…

Occasionally people don't understand how to plug extension power cables together, either, especially during times of high stress and low sleep. Once upon a time, when I was in IT support, I got a call from someone in a satellite office across town saying that their computer wouldn't turn on. A new production had begun and everyone was a bit frantic, so this was an urgent request. After asking them to hold the power s…
But no, turns out someone didnt even manage the basics! LOL
There's a reason the IT Crowd have the running joke of 'have you tried turning it off and on again...'! :-)

All I know is that IPv4 is still around.
And without knowing the IP Addresses of devices on my LAN, by home network would be harder to manage!

I was really hoping for some never before known knowledge of how to connect Extension Cables and Power Boards together! But no, turns out someone didnt even manage the basics! LOL There's a reason the IT Crowd have the running joke of 'have you tried turning it off and on again...'! :-)

But this was what literally happened. All routers today support NAT and most of them actively use it. Isn't it a magical form of extended IPv4 address space? Could have been easily done in less band-aid fashion instead of chasing IPv6.
