ARIN-Issued

Part of the issuance reported the same day

ARIN's statistics show it reserved on 2021-10-04 and allocated (dated 2021-10-05), reserved on 2021-10-06. ARIN removed its own pool record for this range as part of issuing it: the same report adds 23.247.132.0-23.247.135.255, 23.247.136.0-23.247.139.255, 23.247.144.0-23.247.147.255, 23.247.148.0-23.247.151.255 and 15 more. The issuance is explained on those lines.

Estimated hold end 2021-10-19. 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 2013-10-24) on 2021-08-19 and reserved on 2021-08-21. 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 2021-10-19. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2013-10-23 and allocated (dated 2013-10-24) on 2013-10-25. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

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.
