[arin-ppml] IPv6 Non-connected networks

This thread has mostly wondered off of my original question, but it 
still has been an interesting discussion, none the less.

The intent of my question is how do we want to deal with networks that 
are not connected to the Internet.  In other words networks that have no 
intention of achieving global reachability but still many need or want 
globally unique addresses.  ARIN Policy specifically addresses a special 
case of what I am asking about for IPv6 in 6.10.2 Micro Allocation for 
Internal Infrastructure, and it creates a special pool for this use. 
Also, by the fact that current end-user assignments are based on IPv4 
Policy, then section 4.3.5. Non-connected Networks allows such networks 
to get an IPv6 assignment, currently out of a common pool for end-user 

Since I've been working on rewriting ARIN's IPv6 policy I want to know 
how the community want this to actually work, my goal is a more direct 
and clear path for these network to get addresses.  However, I see a 
faction of the ARIN community that want these assignments made from a 
filterable block.  Then, there is another faction that says, wait a 
minute, that means ARIN is defining Routing Policy.

I believe that these network have a right to globally unique IPv6 
addressing just as much as anyone else.  But, personally I'm mostly 
agnostic to the question if the these assignments should be made from a 
block designated for non-connected networks or just assigned from a 
common pool with all other assignments.  I can see valid arguments on 
both sides.

Basically it boils down to, if we assign from a common pool then there 
is no distinction and you can only have the address space you can 
justify connected or non-connected.  If we make a distinction then, 
anyone must to be able to get such a non-connected assignment without 
regard to if they have an assignment intended intended for global 

The current text I have in PP#107 calls for a common pool because that 
seemed most consistent with the current policies as I understand them. 
  But as I said, I'm mostly agnostic on this issue.  So I started this 
thread to try develop a consensus one way or the other.  Because, we 
can't do both at the same time.

So I would like to see continued discussion on the specific issue of a 
common pool for all assignments VS. a specific pool for non-connected 
networks.  Additionally, I intend to raise this issue on the floor in
