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replaces outdated RFC2050 references in Sections 4.2.3.4.1. and 4.2.3.6. 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Section 4.2.3.6 references RFC2050, which is obsolete, and is not synchronized 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 4.2.3.6, 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 4.2.3.6 will simplify the language of 
that section.

 

Replace sections 4.2.3.4.1 and sections 4.2.3.6 with the following text:

 

4.2.3.4.1. 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 issuing them additional space.

 

4.2.3.6. 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 customer. 

 

Timetable For Implementation: Immediate
