Summary

  • ARIN staff say some organizations receiving IPv4 addresses did not realize they generally must wait 12 months before acting as a transfer source.
  • The restriction sits under source conditions in NRPM 8.3 and 8.4. Staff already notify recipients during processing; ARIN is asking whether the recipient text should say it too, and whether early source attempts should prompt a resource review.

An organization can finish an IPv4 transfer, put the confirmation away and still plan its next move on the wrong date. ARIN's Policy Implementation and Experience Report says some recipients did not know they would generally have to wait 12 months before acting as the source of another transfer. Staff notify recipients during the incoming transaction. In the written manual, the warning sits under “Conditions on source of the transfer.” The person signing for addresses today has to read ahead to the role they may take a year from now.

The current ARIN policy manual shows the placement. Sections 8.3 and 8.4 restrict an ARIN-region source that recently received IPv4 resources. The clock is tied to approval of the later outgoing transfer. Section 8.3 has exceptions for mergers and acquisitions and a possible renumbering waiver; 8.4 also specifies common-control cases. The newly received addresses can be used; the condition applies when the organization next asks to transfer resources out.

ARIN now asks two questions. Should the recipient sections repeat the twelve-month rule? And should an organization that tries to transfer out early face an NRPM 12 Resource Review? A mistimed transfer already collides with the source condition; an added review could bring the operator's wider resource record under scrutiny. Neither change was announced as adopted. The presentation counts no surprised recipients or early attempts, so the size of the problem remains a blank cell.

The fix could fit on a transfer confirmation: print the earliest eligible date for a later source request and point to the applicable exceptions. Give the recipient section the same warning. ARIN already knows the date and already tells people. A written record would still be there when a network manager leaves, a new customer asks for space or the next transfer file lands on a different desk. A rule with a timer should come with a clock face.
