[ppml] Revising Centrally Assigned ULA draft

Jordi-  We are saying the same thing.  Just how you get there is different.  

It is true, we could either modify or eliminate the current ARIN policy to work in unison with what might be a finsished RFC on ULA-C.  I just believe that sometimes it is easier to start with a fresh policy.  In this case, I think it would be less confusing to expire the current policy and replace it with a new one that is more fitting as opposed to trying to modify the current one. A modification could quickly confuse anyone who has not been following all of the ULA emails and conversations.

I suppose we can figure this out when we get to that bridge.

Hi Marla,

In fact, when I started to work on this, it was because I realized about the
possibility to use ULA-C as the space for the microallocations and talking
with different folks they said that it will be possible with ULA-C, but not

I also talked with people from the AC and they considered the point (I was
told) to use ULA-C for the microallocations when ULA-C is available.

So my view is that probably the microallocations policy should not expire,
but instead, be modified to make usage of the ULA-C space instead of global
