Inventory
Likely issued from RIPE NCC-controlled inventory

No transfer record matches. The RIPE NCC's statistics show it available on 2019-01-31 and allocated (dated 2019-02-01) on 2019-02-01. The tracker saw this range released from hold on 2018-12-04 (171.22.0.0/16), so it appears to have been issued again from the RIPE NCC's pool.

RDAP lookups

Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
