I did a completely fresh review of the ARIN 40 Policy Experience Report and
the ARIN-2017-9 PPML thread so far. From that, I concluded the best way to
present the question to the community is to use Andrew's updated Problem
Statement with a Policy Statement that modifies section 8.5.4 Initial Block
by providing a /24 for assignments and a /24 up to a /21 for allocations.

Please provide any feedback you might have on the following;

Thanks

Problem Statement:

It was noted in 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 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.

Policy statement:

Replace section 8.5.4 as follows;

8.5.4. Initial block

Organizations without direct assignments or allocations from ARIN qualify
for the transfer of an initial IPv4 block, a /24 for assignments, or a /24
up to a /21 for allocations.
