Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.

2020-09-29 ARIN − Remove Change to ARIN's own pool record Observed only
ARIN-Issued
Remove 136.175.0.0-136.175.255.255
Inventory
Part of the issuance reported the same day

ARIN's statistics show it reserved on 2020-09-28 and allocated (dated 2020-09-29), reserved on 2020-09-30. ARIN removed its own pool record for this range as part of issuing it: the same report adds 136.175.0.0-136.175.1.255, 136.175.4.0-136.175.7.255, 136.175.8.0-136.175.11.255, 136.175.26.0-136.175.26.255 and 16 more. The issuance is explained on those lines. Another change to this range was reported the day before or after (2020-09-30: Remove 136.175.12.0-136.175.15.255; 2020-09-30: Remove 136.175.16.0-136.175.19.255; 2020-09-30: Remove 136.175.40.0-136.175.43.255), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
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 2018-01-12) 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.

No effect on ARIN applicant inventory

ARIN's transfer log records a merger, acquisition or reorganization from Roya Hosting LLC (ARIN) to OppoBox LLC (ARIN) on 2018-02-21 16:11 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 2018-01-11 and allocated (dated 2018-01-12) on 2018-01-13. The tracker saw this range removed from registration on 2017-12-05 (136.175.0.0/16), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2018-01-11 and allocated (dated 2018-01-12) on 2018-01-13. ARIN removed its own pool record for this range as part of issuing it: the same report adds 136.175.0.0-136.175.255.255. The issuance is explained on that line.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics.

ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2018-02-03. This does not confirm availability.

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.
