Likely issued from RIPE NCC-controlled inventory
No transfer record matches. The RIPE NCC's statistics show it available on 2011-12-20 and allocated (dated 2011-12-21) on 2011-12-21. The tracker saw this range removed from registration on 2011-07-06 (37.0.0.0/10), so it appears to have been issued again from the RIPE NCC's pool.
