Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it reserved on 2024-06-05 and assigned (dated 2024-06-06) on 2024-06-07. The tracker saw this range removed from registration on 2023-09-04 (AS55207), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2024-06-05 and assigned (dated 2024-06-06) on 2024-06-07. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS55207. The issuance is explained on that line.

Hold estimate
Estimated hold end 2024-03-04. 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 assigned (dated 2013-04-22) on 2023-09-03 and reserved on 2023-09-05. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed ASNs for 6 calendar months before reissuing them, so the estimated hold end is 2024-03-04. This does not confirm availability.

ARIN's transfer log records a merger, acquisition or reorganization from Griffin Technology (ARIN) to Incipio, LLC (ARIN) on 2018-10-16 17:25 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.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this ASN (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.
