No transfer record matches. ARIN's statistics show it reserved on 2020-04-22 and assigned (dated 2020-04-23) on 2020-04-24. The tracker saw it removed from registration on 2020-01-06 (108 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.

ARIN's statistics show it reserved on 2020-04-22 and assigned (dated 2020-04-23) on 2020-04-24. ARIN removed its own pool record for this range as part of issuing it: the same report adds 198.54.168.0-198.54.169.255. The issuance is explained on that line.

Hold estimate
Estimated hold end 2020-03-06. 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 assigned (dated 2013-08-30) on 2020-01-05 and reserved on 2020-01-07. 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 2020-03-06. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2013-08-29 and assigned (dated 2013-08-30) on 2013-08-31. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

No transfer log has a transfer of any part of this IPv4 range.
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.
