[arin-ppml] Draft Policy ARIN-2017-9: Clarification of Initial Block Size for IPv4 ISP Transfers

It was noted to me by ARIN staff, that this updated problem statement
doesn't accurately reflect ARIN's current practice.  Below I suggest
another updated problem statement.

*Problem Statement: *

It was noted at the ARIN 40 Policy Experience Report, that there is an
inconsistency in the initial block size for ISPs. Section 4.2.2 notes
that the initial ISP block size should be /21 whereas the initial block
size in 8.5.4 is noted as "minimum transfer size" which is effectively a
/24. This causes ISP organizations to be approved for different initial
block size depending on if they first apply apply for a transfer
directly under section 8 or if they apply for a block under section 4. 
This policy is intended to clarify this issue, by setting a consistent
ISP initial IPv4 block size. It was noted that ARIN staff current
operational practice is to allow qualified ISPs an initial /21 for
Section 8 transfers when they first apply and are approved under section
4.  If an organization applies under section 8 first they are initially
qualified for a /24, larger allocations require additional documentation
as noted in 8.5.5.
