Summary

  • ARIN's Advisory Council sent ARIN-2025-1 and ARIN-2025-8 to separate 14-day Last Calls after its 23 October meeting; both close on 11 November.
  • The first rewrites who the Number Resource Policy Manual calls an LIR or ISP. The second would put “within the ARIN service area” into the rule for IPv4 allocations that facilitate IPv6 deployment.

Two policy files reached the same desk on Wednesday. One asks which organisations fit a registry label. The other asks where a specially reserved block may be used. ARIN's Advisory Council gave both a Last Call ending 11 November. A university holding a direct allocation will read the first for its obligations to document customer assignments. An applicant seeking the special 4.10 reserve for a deployment outside ARIN’s region will read the second for the proposed place-of-use rule.

ARIN-2025-1 tackles the policy manual's vocabulary. A Local Internet Registry, or LIR, receives numbers from a Regional Internet Registry, or RIR, and allocates them onward. The proposed definition requires RIR membership and an allocation; it names large enterprises, universities and Internet Service Providers, or ISPs, as possible examples. A new ISP definition covers services from connectivity to colocation and virtual private networks. The text also changes numerous references from ISP to LIR. Take Section 4.2.3.1: its proposed wording requires LIRs to keep justification for each customer reassignment or reallocation, which ARIN may request before future allocations. A university with directly allocated space can now see itself named in that obligation; the current ISP wording makes the connection harder to read. The proposal describes a clearer subject for the rule, not a new allocation granted by a label.

ARIN-2025-8 is shorter and sharper. It would add “within the ARIN service area” to the sentence dedicating Section 4.10 IPv4 space to IPv6 deployment. The existing sentence does not say that. ARIN's problem statement says staff has already read the rule as limiting this space to regional use. Last Call puts the proposed restriction in front of the community as actual policy language, where opponents can contest a boundary rather than an interpretation.

The Advisory Council's result keeps ARIN-2025-3 and ARIN-2025-7 on its work list. These two files alone got the 14-day clock. Comments go to the Public Policy Mailing List. After the window, the policy process gives the Council a route to recommend text to the Board. For now, the consequential fact is the opened window: a term of membership in one file and a geographic condition in the other are being written into the rules at the same time.
