Recommended Draft Policy ARIN-2020-5: Clarify and Update Requirements 
for Allocations to Downstream Customers

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

This Draft Policy is fair, impartial, and technically sound. This draft 
policy replaces outdated RFC2050 references in Sections and with references to the end user assignment utilization 
requirements in Section 4.3.3.

Problem Statement:

A recent Policy Experience Report demonstrated the fact that the 
existing Section references RFC2050, which is obsolete, and is 
not synchronized with utilization requirements carried in Section 4.3.3, 
specifically the utilization rate.

Policy Statement:

Given that RFC7020, which supercedes RFC2050, no longer carries specific 
utilization requirements for downstream customers of ISPs, its reference 
may be removed from Section, instead referencing 4.3.3 
(currently, 50% utilization within 24 months) to harmonize the 
utilization requirements of both ISPs and their downstream customers.

Removing these references from Section will simplify the 
language of that section.

Replace sections and sections with the following text: Utilization

A downstream customer requesting address space from an upstream ISP must 
document a plan to the allocating ISP for their utilization to conform 
to Section 4.3.3. Reassignment and reallocation information for prior 
allocations must show that each customer meets the 80% utilization 
criteria and must be available via SWIP / a distributed service which 
meets the standards set forth in section 3.2 prior to your issuing them 
additional space. Reassignments to Multihomed Downstream Customers

If a downstream customer has a requirement to multihome, that 
requirement alone will serve as justification for a /24 allocation. 
Downstream customers must provide contact information for all of their 
upstream providers to the ISP from whom they are requesting a /24, and 
utilize a border routing protocol between the customer and the ISP. 
Customers may receive a /24 from only one of their upstream providers 
under this policy without providing additional justification. ISPs may 
demonstrate they have made an assignment to a downstream customer under 
this policy by supplying ARIN with the information they collected from 
the customer, as described above, or by identifying the AS number of the 

Timetable for Implementation: Immediate
