ARIN's transfer log records a merger, acquisition or reorganization from Open Text Corporation (ARIN) to Open Text Corporation (ARIN) on 2019-01-22 17:21 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.

Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it reserved on 2018-07-29 and assigned (dated 2018-07-30) on 2018-07-31. The tracker saw this range removed from registration on 2013-02-21 (AS31917), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2018-07-29 and assigned (dated 2018-07-30) on 2018-07-31. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS31917. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2013-08-21. 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 2004-01-22) on 2013-02-20 and not issued on 2013-02-22. (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 2013-08-21. 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.
