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.

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it reserved on 2019-01-13 and allocated (dated 2019-01-14) on 2019-01-15. The tracker saw this range released from hold on 2019-01-11 (168.151.12.0-168.151.15.255), so it appears to have been issued again from ARIN's pool.

Part of the issuance reported the same day

ARIN's statistics show it reserved on 2019-01-13 and allocated (dated 2019-01-14) on 2019-01-15. ARIN removed its own pool record for this range as part of issuing it: the same report adds 168.151.12.0-168.151.15.255. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2017-02-04. 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 1994-04-04) on 2016-12-05 and reserved on 2016-12-07. 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 2017-02-04. This does not confirm availability.

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.
