Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.

No transfer record matches. ARIN's statistics show it reserved on 2025-06-30 and allocated (dated 2025-07-01) on 2025-07-02. The tracker saw this range removed from registration on 2024-10-07 (45.45.195.0/24), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2025-06-30 and allocated (dated 2025-07-01) on 2025-07-02. ARIN removed its own pool record for this range as part of issuing it: the same report adds 45.45.195.0-45.45.195.255. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2024-12-06. Possible reissue candidate after this date; not confirmed available.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it allocated (dated 2021-07-09) on 2024-10-06 and reserved on 2024-10-08. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2024-12-06. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2021-07-08 and assigned (dated 2021-07-09) on 2021-07-10. The tracker saw this range released from hold on 2021-07-07 (45.45.128.0-45.45.255.255), so it appears to have been issued again from ARIN's pool.

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.
