Draft Policy ARIN-2024-5: Rewrite of NRPM Section 4.4 Micro-Allocation

Problem Statement:  

The current NRPM Section 4.4 language hasn’t aged well. As the ARIN 53 policy experience report demonstrated, 4.4 has also become difficult to implement by ARIN staff. The growth and use of Internet Exchanges have also changed. The overhaul seeks to improve technical soundness, respect the privilege of a dedicated pool and to more closely observe conservation principles using clear, minimum and enforceable requirements and underscoring the value of routability of allocated prefixes as required.

Policy Statement:  

4.4 Critical Internet Infrastructure (CII) Allocations

ARIN will reserve a /15 equivalent of IPv4 address space for Critical Internet Infrastructure (CII) within the ARIN RIR service area. Allocations from this pool will be no smaller than a /24. Sparse allocation will be used whenever practical. CII includes Internet Exchanges, IANA-authorized root servers, TLD operators that offer domain-level DNS services to outside parties, ARIN, and IANA.

Addresses allocated from this pool may be revoked if they are no longer in use or not used for approved purposes. Only Section 8.2 transfers are allowed. Use of this policy for CII is voluntary. ARIN will publish all 4.4 allocated addresses for research purposes.

4.4.1 Internet Exchange Allocations

Internet Exchange operators must justify their need by providing a minimum of three initial participants not under common control connected to a shared, physical switching fabric to be used for the purpose of the exchange of data destined for and between the respective networks. This justification must include participant names, ASNs and contact information for each named participant. The applicant’s Internet Exchange affiliated ASNs are not eligible to be included in meeting the participant requirement.

Allocated addresses may be publicly reachable at the operator’s discretion, but must be assigned only to resources required to operate the IXP.

4.4.2 TLD Allocations

TLD operators will provide justification of their need and certification of their status as currently active zone operators.

4.4.3 Additional Requests

A recipient may request up to a /24-month supply of IPv4 resources under this section. To qualify for additional resources, a recipient must have utilized all other resources allocated via 4.4, in aggregate, to at least 80%, and at least 50% of each individual prior allocation.

Timetable for Implementation: Immediate
