Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it available on 2018-04-15 and assigned (dated 2018-04-16) on 2018-04-17. The tracker saw this range released from hold on 2018-04-13 (AS23293), 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 2018-04-12 and available on 2018-04-14. 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 2017-10-30, 165 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Hold estimate
Estimated hold end 2018-04-30. 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 2011-02-02) on 2017-10-29 and reserved on 2017-10-31. 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 2018-04-30. This does not confirm availability.

Hold estimate
Estimated hold end 2010-12-16. 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 2007-10-10) on 2010-06-15 and not issued on 2010-06-17. (Until 2013-03-05, ARIN's statistics list only what's issued.) 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 2010-12-16. This does not confirm availability.

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.
