Hold estimate
Estimated hold end 2025-01-10. 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 2018-06-27) on 2024-11-10 and reserved on 2024-11-12. 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 2025-01-10. This does not confirm availability.

ARIN's transfer log records a transfer from Net3 Inc. (ARIN) to LightWave Networks (ARIN) on 2018-06-27 14:54 UTC. ARIN-Issued lists it as "Add" because the registration changed hands; it is not a new allocation from ARIN.

Classification history for this change (4 versions)
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.
