Re: IPv6 addresses really are scarce after all

perhaps, but one might also reasonably expect 2^0 networks to be
insufficient.


At the risk of repeating myself, I respectfully disagree.  Given that you
can reasonably build a flat subnet of 1000 hosts today, it does
not seem like an unreasonable entry point.  Mom & Pop 6-pack
have one computer.  George & Jane Jetson only have 6.  Why
does the entry point have to be more than two orders of
magnitude above the common case?
you seem to be stuck in the 20th century. where do you get the idea that
IPv6 is only going to be used (or even, mostly going to be used) for
things that resemble desktop PCs?  desktop PCs are dinosaurs nearing
extinction, and early indications are that homes are going to have
multiple kinds of wireless networks.  bridges between dissimilar media
don't always work so well.  and given the range of some of those media,
it should not be assumed that everything within a "home" will be in the
same layer 2 segment.

IPv6 needs to last a lot longer than IPv4.  it shouldn't be constrained
to fit yesterday's notions of what's reasonable.

so are prefix allocations to users of less size than a /48.  but if ARIN
can't follow the specifications that everyone else uses, this should
call their competence into serious question, and maybe IANA should find
someone else to dole out IPv6 prefixes for that part of the world.
Once again, that's the MSO's doing that, not ARIN.
whoever is doing it needs to stop, or be stopped.
