Re: IPv6 addresses really are scarce after all

2007-08-18 16:37:01

The issue is that IPv6 is architected to give sufficient addresses to
end users, and by screwing with this ARIN is harming both deployability
of IPv6, manaegability of IPv6, and usability of IPv6 by applications.


First, there was never an architectural goal to give end users
'sufficient' addresses
for arbitrary values of 'sufficient'.  Second, one might reasonably
expect 2^64
addresses to be sufficient.  
perhaps, but one might also reasonably expect 2^0 networks to be
insufficient.
It allows anyone to embed 2^32 entire IPv4-sized Internets
in their own house.  If you have a problem with IPv6's routing
architecture not allowing
subnetting within the least significant 64 bits, well, that's water
that's VERY much
under the bridge.
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.
Third, I think you have your perpetrator's confused.  ARIN is not
limiting end users
to /64's, that is the MSOs call.  They are retailing service and as
you might reasonably
expect, their entry level product is just that: entry level.  As I
mentioned before, if you
want more, fork over more sheckles.
ARIN does not have a license to print money at the expense of the
Internet architecture.
