The RIPE NCC's transfer log records a transfer from an unnamed organization (ARIN) to TWT S.p.A. (RIPE NCC) on 2020-02-03 19:00 UTC: it came to the RIPE NCC from ARIN. It was already issued by another registry, so this is not a new issuance.

ARIN's transfer log records a merger, acquisition or reorganization from Serverlogy Corporation (ARIN) to Serverlogy Corporation (ARIN) on 2019-11-26 13:03 UTC. The registration changed hands; it is not a new allocation from ARIN. ARIN-Issued and ARIN's statistics don't show this change; only the transfer log records it.

No transfer record matches. ARIN's statistics show it available on 2015-03-26 and allocated (dated 2015-03-27) on 2015-03-28. The tracker saw this range released from hold on 2011-08-03 (45.2.0.0-45.255.255.255), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it available on 2015-03-26 and allocated (dated 2015-03-27) on 2015-03-28. ARIN removed its own pool record for this range as part of issuing it: the same report adds 45.33.224.0-45.33.239.255. The issuance is explained on that line.

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.
