> Something that isn't talked much about IPv6 and I believe has subtle and indirect influence on it's adoption is that it is far far far less human-readable than IPv4.

No shit Sherlock: an IPv4 is 4 bytes. An IPv6 requires 16. This is four times as much data, it has to be less readable, that’s just the price of a bigger address space.

Now one could have argued that 8 bytes, heck, even 6 bytes, would have been enough. I guess it would have, but having a /48, or even a /64 range, per user, is quite convenient: we can ditch the NAT (we probably won’t, but we can).

But even then, 8, or even 6 bytes, remain harder to read than 4.
