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

Looking back, I note that I have not made an ISP initial IPv4
request after 02/21/2017 when the policy was changed.

My previous ISP initial IPv4 requests asked for a
3 month, 12 month, and 18 month projection.

I assumed this was to comply with " Three Months"
that existed until 02/21/2017.

Was this information used prior to 02/21/2017?
Is this information used since 02/21/2017?

Or is it ignored and collected only because the
initial ISP  IPv4 request uses the same form as the
subsequent  requests?

" Three Months" disappeared on 02/21/2017

That version was modified by:

2016-4 replaces section 4.2.2 text.

It does not clearly state that it
replaces, removes, or modifies
any of the sub sections. ISP Requirements Use of /24 Efficient Utilization Three Months Renumber and Return [Section Number Retired]

I never noticed that the sub-section disappeared
and assumed 2016-4 only changed the 4.2.2

When I voiced my support for the 2016-4 it was
with the understanding that (at that time):

An ISP without a direct IPv4 block would
automatically qualify for a /24, (without needing
to go to an upstream and get IPv4 space and
pressing it into service).

Furthermore an ISP without a direct IPv4 block
could get more than a /24 so long as it was did
not exceed a 90 day supply (for non-transfers)
or a 2 year supply (for transfers).

Staff understanding at the time, suggested
the same conclusions.
