Likely issued from RIPE NCC-controlled inventory
No transfer record matches. The RIPE NCC's statistics show it available on 2023-03-06 and allocated (dated 2023-03-07) on 2023-03-07. The tracker saw this range released from hold on 2023-03-06 (185.135.44.0/22), 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 (2023-03-06: Released 185.135.44.0/22), 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.
