Re: I think I know why
"but that's not what the industry want, I guess, especially since they see a delicious opportunity to track each single device on the internet."
I hadn't thought of that aspect.
If I ever shift my LAN to IPv6 (I don't know why I would, but just for the sake of argument), my LAN would still go through a router doing NAT, specifically so that my entire LAN only presents a single IP address to the rest of the world.
The less the world can tell about my network configuration, the better.
