If an organization, whether a member or non-member, ISP or end-user, relinquishes a group of portable, non-aggregatable address blocks to ARIN, they shall be allowed to receive a block in exchange, /24 or shorter, but no more than the shortest block that could contain all of the returned blocks. Exchanged space shall be returned within 12 months. If the gain in the number of addresses is greater than 4096, the aggregation request must be evaluated by the ARIN in accordance with the current IPv4 allocation policy. If all of the previous address blocks were maintained in the ARIN database without maintenance fees, the replacement space shall be as well, but if any one of the returned blocks had associated maintenance fees, then the replacement block shall also be subject to maintenance fees.
