No transfer record matches. ARIN's statistics show it reserved on 2023-04-04 and allocated (dated 2023-04-05) on 2023-04-06. The tracker saw this range released from hold on 2023-04-03 (104.167.244.0-104.167.244.255), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2023-04-04 and allocated (dated 2023-04-05) on 2023-04-06. ARIN removed its own pool record for this range as part of issuing it: the same report adds 104.167.244.0-104.167.244.255. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2022-08-05. 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 2021-01-19) on 2022-06-05 and reserved on 2022-06-07. 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 2022-08-05. 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.
