Earlier quoted context omitted.
I recently troubleshot an installation for someone where at some point in the past they'd picked 1.1.1.0/24 as their address range because "all that 192 stuff was silly and too complicated". You know, I'm not sure I can explain how I feel about this properly without waving the shotgun around.
Yet another thing ipv6 solves. Yeah you can do the officially supported fdXX:XXXX:XXXX:... but you can also just pick something like 1::1 and it's unlikely to conflict with the current global range. If you're gonna do that, though, it's better if you use fd00:... or one of the other assigned ranges so it's still in the standard range. OSes use this as a heuristic for source address selection.
I'm not familiar with IPv6's details, could you elaborate on this? To me, this reads like you're saying that IPv6 solves the problem by having low adoption rates rather than an actual function of the protocol.
