Draft Policy ARIN-2025-8

Reserve 4.10 Space for In-Region Use

Status: Under Discussion
Shepherds: Kendrick Knowles, Kaitlyn Pellak

Current Text (14 July 2025)

Problem Statement:

ARIN 4.10 allocations, reserved to facilitate IPv6 deployment, currently have no restrictions for out-of-region use beyond the general restrictions laid out in Section 9. As the use of these allocations outside of the ARIN region seems to be contrary to the intentions for use of this space - and ARIN staff has interpreted the policy as such - the prohibition of this practice should be codified in policy.

Policy Statement:

Change the second sentence in NRPM Section 4.10 from:

“This IPv4 allocation will be set aside and dedicated to facilitate IPv6 deployment.”

to:

“This IPv4 allocation will be set aside and dedicated to facilitate IPv6 deployment within the ARIN service area”

Timetable for Implementation: Immediate

Comments: This proposal was prompted by community feedback to Registration Services, as reported in the ARIN 55 Policy Experience Report. ARIN staff has indicated that there is no intention to extend this restriction to 4.10 allocations assigned before the implementation of this policy.

Staff and Legal Review (12 November 2025)

Staff Understanding: The current implementation of Section 4.10 (Dedicated IPv4 Allocations to Facilitate IPv6 Deployment) requires that IPv4 addresses be used within the ARIN region. Draft Policy ARIN-2025-8: Reserve 4.10 Space for In-Region Use codifies the current practices applied by ARIN staff when processing requests under Section 4.10. This policy does not alter existing review practices; it formally documents the longstanding approach ARIN staff has used and will continue to apply.

Implementable as Written?: Yes

Impact on ARIN Registry Operations and Services: None

Legal Review: No material legal issue

Implementation Timeframe Estimate: 3 months

Implementation Requirements:

• Staff Training
• Updates to public documentation
• Updates to internal procedures and guidelines
