Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it reserved on 2016-10-19 and assigned (dated 2016-10-20) on 2016-10-21. The tracker saw this range released from hold on 2016-10-19 (AS394003), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2016-10-19: Remove AS394003), so the before-and-after statistics may include it.

ARIN's statistics now list it as 'available'; reissue not confirmed
ARIN's statistics show it reserved on 2016-10-18 and available on 2016-10-20. 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 2016-08-04, 76 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2016-10-20: Add AS394003), so the before-and-after statistics may include it.

Hold estimate
Estimated hold end 2017-02-04. 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 2015-05-19) on 2016-08-03 and reserved on 2016-08-05. 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 2017-02-04. This does not confirm availability.

Transfer records
No transfer log has a transfer of any part of this ASN.
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.
