ARIN's statistics show it reserved on 2024-10-02 and allocated (dated 2024-10-03) on 2024-10-04. ARIN removed its own pool record for this range as part of issuing it: the same report adds 216.116.136.0-216.116.139.255, 216.116.140.0-216.116.143.255. The issuance is explained on those lines.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2024-02-10. 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 2015-04-28) on 2023-12-11 and reserved on 2023-12-13. 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 2024-02-10. This does not confirm availability.

No transfer record matches. ARIN's statistics show it reserved on 2015-04-27 and assigned (dated 2015-04-28) on 2015-04-29. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

ARIN's statistics show it reserved on 2015-04-27 and assigned (dated 2015-04-28) on 2015-04-29. ARIN removed its own pool record for this range as part of issuing it: the same report adds 216.116.136.0-216.116.143.255. The issuance is explained on that line.

ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2010-12-01 and not issued on 2010-12-03. (Until 2013-03-05, ARIN's statistics list only what's issued.) The registry's pool records from that time aren't public, so the tracker can't tell what was removed.

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.
