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.

Hold estimate
Estimated hold end 2025-04-06. 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 2018-09-28) on 2025-02-04 and reserved on 2025-02-06. 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 2025-04-06. This does not confirm availability.

No effect on ARIN applicant inventory

No transfer record matches. ARIN's statistics show it reserved on 2018-09-27 and allocated (dated 2018-09-28) on 2018-09-29. The tracker saw it removed from registration on 2015-08-11 (1144 days earlier), and it is back with the same holder record it had before, so it went back to its previous holder rather than to a new one: most likely a suspension lifted, a reinstatement or a correction.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2015-10-10. 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 2013-11-01) on 2015-08-10 and reserved on 2015-08-12. 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 2015-10-10. 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.
