Yep, it's tragic because it all stems from unforced differences vs ipv4. The design was reasonable, but with perfect hindsight, it needed to be different. They needed to keep the existing /32s and just make the address field bigger, despite the disadvantages. "Everywhere but nowhere" is sorta how I'd describe ipv6. Most hardware and lower-level software supports it, so obviously it wasn't impossible to support a new…

I would love to have seen the world in which that happened, and where all the other parts of IPv6 were independently proposed (and likely many of the…
