ARIN-prop-347: Reserve 4.10 space for In-Region Use

Date: 14 July 2025

Proposal Originators: Chris Woodfield

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.
