[ppml] Policy Proposal: IPv6 Assignment Guidelines - version 3

[cja@daydream.com]

Michael,

There are some who say that we do know the right thing with allocation
policies for IPv6 but we're doing something else anyway.  Who knows.

I do know this.  We need to have a policy for subsequent allocations now.
This is just like when Jon Postel set aside 24.0.0.0/8 for cable.  My
organization got 24.0.0.0/14.  No one at the Internic or IANA thought that
we would ever come back for more.  There was no policy.  The reality is that
we did go back for more over and over again.  We used a lot of address space
and it was highly utilized.  When we went back for more we spent quite a bit
of time with Kim and Jon sorting out a reasonable subsequent allocation
policy for cable (one that is still in use and it has been over 10 years).

I do realize that 24.0.0.0/14 is small compared to an IPv6 allocation but
for its time it was huge.  Someone will come back for more whether it's a
reasonable request or not and we have to be ready.
