[ppml] Policy Proposal: IPv6 Assignment Guidelines

If we move into this direction, we should also change the global policy and
get the RIRs returning the /12 to IANA, and make a new default allocation.

I think this is a ridiculous discussion. /48 should be the default and in
fact never APNIC and ARIN should have gone to the /56. RFC3177 is clear.

I remember when I was accused about trying to go against the system with the
ULA-C thing, however we go against the system with all this, because the
system is /48, according to RFC3177. And even if the RFC is not there, is
quite logic that /48 is enough for all the cases, and we should not start
with barriers or ultra-conservation mind-set as in IPv4. The change in the
HD-ratio was perfect enough to get IPv6 for around 480 years if I recall
correctly Tony Hain calculation. I'm happy if it last only 100 years,
because I'm sure we will have something new by then anyway, for many other
reasons than addressing space.

LIRs/ISPs should provide a /48 to all customers, no justification, no extra
cost. The value of the service must come from other applications and
services still to come, but they will never come if we fall again into the
ultra-conservation thing.
