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.
ARIN's transfer log records a transfer from TNEXT Communication Inc (ARIN) to TechMinds Enterprise Inc. (ARIN) on 2025-08-11 18:49 UTC. ARIN-Issued lists it as "Add" because the registration changed hands; it is not a new allocation from ARIN.

No transfer record matches. ARIN's statistics show it reserved on 2020-06-24 and allocated (dated 2020-06-25) on 2020-06-26. The tracker saw this range released from hold on 2020-06-24 (139.64.128.0-139.64.255.255), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2020-06-24: Remove 139.64.128.0-139.64.255.255), so the before-and-after statistics may include it.

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.
