Re: Dear network geeks, IPv6 is crap because...
You should be getting enough address space to not need to NAT on v6, and if you do so anyway then you've brought all of the associated problems onto yourself, so you don't get to complain about them. This is, after all, kinda the reason v6 was designed with enough address bits in the first place (this plus routing aggregation).
Meanwhile v4 on NAT is necessary for the vast majority of people. That's why I'm doing the comparison between v4+NAT vs v6 without NAT.
