Recommended Draft Policy ARIN-2019-8: Clarification of Section 4.10 for 
Multiple Discrete Networks

AC Assessment of Conformance with the Principles of Internet Number 
Resource Policy:

The Advisory Council moved ARIN-2019-8 Clarification of section 4.10 for 
Multiple Discrete Networks to recommended draft status. The proposed 
policy will enable fair distribution of resources, is technically sound, 
and has received support from the community.

Problem Statement:

Currently, applicants for IPv4 resources under section 4.10 of the NRPM 
who do so under a single OrgID of the NRPM may only obtain one /24 every 
six months for the OrgID, even in the case where multiple discrete 
networks (MDNs) as defined in section 4.5 of the NRPM are grouped under 
that OrgID. On the other hand, where MDNs are held under different 
OrgIDs associated the same entity, the six-month constraint would apply 
to each discrete network separately. This results in unfair allocations 
of resources based solely on how entities choose to associate MDNs with 
their OrgIDs. This policy rectifies that problem by placing MDNs on an 
equal footing for the purpose of section 4.10 allocations regardless of 
how they are grouped by OrgID by the same ultimate entity.

Policy Statement:

Bullet 1. under section 4.10 of the NRPM is amended to read:

the applicant may not have received resources under this policy in the 
preceding six months, except to the extent that the applicant is 
requesting resources for a discrete network in respect of which it has 
not received any resources under this policy in the preceding six months;

Add a new bullet 6 that reads:

An applicant requesting multiple allocations under this policy to 
support Multiple Discrete Networks, as defined under Section 4.5, may 
not receive more than the equivalent of a /21 of IPv4 address space in 
any one six-month period hereunder.


Timetable for implementation: Immediate

Anything Else

To what extent should the passage of this policy be contingent or 
independent of whether any ultimate cap is imposed on the total quantity 
of IPv4 resources that an entity can obtain under section 4.10 
regardless of the number of OrgIDs associated with the entity or number 
of MDNs it holds.
