Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it available on 2017-12-14 and assigned (dated 2017-12-15) on 2017-12-16. The tracker saw this range released from hold on 2017-11-08 (AS40001), so it appears to have been issued again from ARIN's pool.

ARIN's statistics now list it as 'available'; reissue not confirmed
ARIN's statistics show it reserved on 2017-11-07 and available on 2017-11-09. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. The tracker saw it removed from registration on 2017-08-22, 78 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2018-02-22. 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 2006-06-05) on 2017-08-21 and reserved on 2017-08-23. 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 2018-02-22. This does not confirm availability.

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.
