[arin-ppml] Revised - Draft Policy ARIN-2024-5: Rewrite of NRPM Section 4.4 Micro-Allocation

[Chris Woodfield]

Hi PPML:

As an FYI, this update to the proposal is the result of ARIN’s Staff & Legal review, which recommended these modifications:

- Removal of the mention of 8.2 transfers as the only valid transfer, as this is covered by the prohibitions in sections 8.3 and 8.4.

- Updating wording in 4.4 clarifying that allocations must continue to meet justification requirements going forward.

- Referencing Section 4.2.41 in Section 4.4.3, instead of duplicating its text.

- Typo fixes.

Please discuss :)

Thank you,

-Chris Woodfield

> 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.

> 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.

> 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.
