On: The world in which IPv6 was a good design (2017)

I think it was obvious in the mid to late 90's that ipv6 was flawed once the internet for civilians really started to take off, not having a seamless migration path was not on.

A seamless migration path (in the sense that you seem to be wanting it) was impossible. v4's design doesn't allow for it.

And your basing this on?

My knowledge of v4's design. The header fields for source and destination address are 32 bits wide, and the pigeonhole principle stops you from fitting more than 32 bits of addresses into those fields.
