ARIN's statistics show it reserved on 2020-06-23 and allocated (dated 2020-06-24), reserved on 2020-06-25. ARIN removed its own pool record for this range as part of issuing it: the same report adds 139.64.128.0-139.64.131.255, 139.64.132.0-139.64.135.255, 139.64.136.0-139.64.139.255, 139.64.150.0-139.64.151.255 and 13 more. The issuance is explained on those lines. Another change to this range was reported the day before or after (2020-06-25: Remove 139.64.153.0-139.64.153.255; 2020-06-25: Remove 139.64.196.0-139.64.199.255; 2020-06-25: Remove 139.64.201.0-139.64.201.255), so the before-and-after statistics may include it.

Hold estimate
Estimated hold end 2019-02-25. 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 2017-09-08) on 2018-12-26 and reserved on 2018-12-28. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2019-02-25. This does not confirm availability.

ARIN's transfer log records a merger, acquisition or reorganization from Univera Network (ARIN) to OppoBox LLC (ARIN) on 2018-06-05 18:14 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 2017-09-07 and allocated (dated 2017-09-08) on 2017-09-09. The tracker saw this range released from hold on 2015-04-01 (139.64.0.0-139.64.255.255), so it appears to have been issued again from ARIN's pool.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (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.
