I remember trying to wrap my head around it close to 20 years ago back in tech school & while i know IPv6 is used out in the real world at the ISP/backbone level, every corporation I’ve ever worked for uses a class A IPv4 network internally (and maybe a few class D’s too). every network I’ve ever used at home is class C IPv4.
IPv6 is some nebulous thing that exists but I’ve never needed to do anything with it…
The good thing is that for most people IPv6 happens and is used transparently. They don’t notice whether and how their web-browser and OS uses IPv6 or IPv4.
IPv6 certainly introduced additional complexity to networking, network routing/decision-making, and administration. But it was/is a technical necessity.
