Likely issued from RIPE NCC-controlled inventory
No transfer record matches. The RIPE NCC's statistics show it available on 2019-05-05 and allocated (dated 2019-05-06) on 2019-05-06. The tracker saw this range released from hold on 2019-05-05 (213.170.212.0/22), so it appears to have been issued again from the RIPE NCC's pool. Another change to this range was reported the day before or after (2019-05-05: Released 213.170.212.0/22), so the before-and-after statistics may include it.

The RIPE NCC's statistics now list it as 'available'; reissue not confirmed
The RIPE NCC's statistics show it reserved on 2019-05-04 and available on 2019-05-05. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2019-05-06: Added 213.170.212.0/22), so the before-and-after statistics may include it.

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.
