Ahh, the 90s. No need for NAT yet.
The world was smaller then. Or maybe there was just less in it?

The man is correct: This is class-based allocations all over again.
On purpose. After watching class-based allocations crash and burn.
One who believes history repeats itself will think that this will only
end in pain. If anything, only the timescales change.
One who believes themselves to be above the mistakes of the past will
of course think this plan is totally without precedent for flaw.
Never between these two beliefs shall we meet. I think Ricky and
Iljitsch are discovering this.

Actually it goes further back than rarp; IPv6 RA is actually more
closely related to IPv4 ICMP Router Advertisements (itself a very
RIP-like way to give only default routes), extended to also carry
RIP-like local-prefix routes. Let's just say it's a slightly
restricted (feature-limited?) RIP. So, start with that and add RARP-
like features with (more complicated) client-based algorithms, and
you've got the picture.
But yeah, in that the static->RARP->BOOTP->DHCP progression was a
dialogue between operators and IETF, IPv6 has basically thrown that
dialogue out with the bathwater, and we're having it all over again.
