No effect on ARIN applicant inventory
No transfer record matches. ARIN's statistics show it reserved on 2020-02-18 and assigned (dated 2020-02-19) on 2020-02-20. The tracker saw it removed from registration on 2017-04-11 (1044 days earlier), and it is back with the same holder record it had before, so it went back to its previous holder rather than to a new one: most likely a suspension lifted, a reinstatement or a correction.

ARIN's statistics show it reserved on 2020-02-18 and assigned (dated 2020-02-19) on 2020-02-20. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS19111. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2017-10-11. 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 2016-02-01) on 2017-04-10 and reserved on 2017-04-12. 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 2017-10-11. This does not confirm availability.

Hold estimate
Estimated hold end 2010-01-14. 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 2000-11-20) on 2009-07-13 and not issued on 2009-07-15. (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 2010-01-14. 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.
