[arin-ppml] Multi-homing justification removed?

Steve,

I think your interpretation of 4.3.2.2 is incorrect.  That policy section
was not the one that authorized the receipt of a (PA) /24 for multihoming.
That was, and still is, 4.2.3.6:
https://www.arin.net/policy/nrpm.html#four236, which states that "The ISP
will then verify the customer's multihoming requirement and may assign the
customer a /24, based on this policy."

4.3.2.2 states that the minimum allocation size (from ARIN) for multihomed
end users was a /24.  However, that did not allow you to get a /24 from
ARIN just by becoming multihomed. If you were/are in that situation, you
always had to (and still have to) get your /24 from your upstream if you
don't meet ARIN's /24 utilizatinon criteria, and demonstrate efficient
utilization before getting one from ARIN.

If my understanding does not match how policy was implemented by staff
prior to implementation of ARIN-2014-13 on 17 September 2014, someone
please correct me, but that was the intent of the policy as I understand it.

When discussing 2014-13, my sense of the community was that we did not want
to authorize receipt of a /24 from ARIN solely based on multihoming,
because that could possibly open up a land rush of organizations spun up
solely for the purpose of getting a /24 from the free pool, holding it for
the requisite time, and then selling it on the transfer market.  I
personally would be more amenable to considering a policy change to
liberalize the requirements for getting a /24 if/when they're available
from the transfer market only.
