Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it reserved on 2021-04-27 and allocated (dated 2021-04-28) on 2021-04-28. The tracker saw this range removed from registration on 2020-07-15 (131.255.16.0/22), so it appears to have been issued again from LACNIC's pool.
