The RIPE NCC's transfer log records a transfer from Kichuk Olha Yuriivna (RIPE NCC) to MLL Telecom Ltd. (RIPE NCC) on 2020-04-09 19:00 UTC. The registration changed hands; it is not a new allocation from the RIPE NCC.

No transfer record matches. The RIPE NCC's statistics show it available on 2018-02-18 and allocated (dated 2018-02-19) on 2018-02-19. The tracker saw this range released from hold on 2018-02-18 (185.17.96.0/22), 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 (2018-02-18: Released 185.17.96.0/22), 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 2018-02-17 and available on 2018-02-18. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2015-03-13, 1073 days earlier. 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 (2018-02-19: Added 185.17.96.0/22), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2015-09-09. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it allocated (dated 2013-01-29) on 2015-03-12 and reserved on 2015-03-13. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC holds returned, revoked and reclaimed IPv4 space for 180 days (six months), or longer while still routed, before reissuing it, so the estimated hold end is 2015-09-09. This does not confirm availability.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.
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.
