Policy statement:

4.3.6 Additional Assignments

In order to justify an additional assignment, end-users must have efficiently utilized at least 80% of all previous assignments, and must provide ARIN with utilization details. The prefix size for an additional assignment is determined by applying the policies found in Section 4.3 of the NRPM.


There are no published criteria for additional assignment requests from end-user networks. NRPM 4.3 seems to only cover initial assignments. NRPM 4.3.3 states, in part, "Requesters must show exactly how previous address assignments have been utilized and must provide appropriate details to verify their one-year growth projection." Unfortunately, the above text does not specify any metrics for ARIN staff to apply when determining if an additional assignment is justified. Though most end-users only get one assignment, some end-users request a 2nd or 3rd or Nth assignment.

Currently, the ARIN staff applies what they perceive to be "efficient utilization" criteria; for instance, the end-user must have utilized at least 80% of last assignment and must provide ARIN with utilization details.

Timetable for implementation: Immediate
