[arin-ppml] Policy Proposal: Waiting list for unmet IPv4 requests

Ah, ok. So you're saying that the request must be revalidated only at
the time the numbers become available? That actually is simpler, and I
hadn't thought of it. Thanks.
The only possible downside I can think of is that someone might think
that they've already gotten approved for addresses, and then be
surprised when the addresses come available that they no longer qualify
because something has changed. That should be manageable with
reasonable expectations-setting, though...
I'm not sure we want to completely remove the transfer clause. For
example, consider an entity that qualifies for a /18 of space. They
only ask for a /20, though, and get put on the waiting list. If they
subsequently go get a /19 through transfer, they would still qualify for
a /20, but IMO they should lose their place on the waiting list and have
So the resulting language might look something like this?
22.214.171.124 Waiting list
The position of each qualified request on the waiting list will be
determined by the date it was approved. Each organization may have one
approved request on the waiting list at a time.
126.96.36.199 Fulfilling unmet needs
As address blocks become available for allocation, ARIN will fulfill
requests on a first-approved basis, subject to the size of each
available address block and a re-validation of the original request.
Requests will not be partially filled. Any requests met through a
transfer will be considered fulfilled and removed from the waiting list.
