No transfer record matches. ARIN's statistics show it reserved on 2020-01-29 and allocated (dated 2020-01-30) on 2020-01-31. The tracker saw this range released from hold on 2019-12-17 (204.235.105.0-204.235.105.255), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2020-01-29 and allocated (dated 2020-01-30) on 2020-01-31. ARIN removed its own pool record for this range as part of issuing it: the same report adds 204.235.105.0-204.235.105.255. The issuance is explained on that line.

Hold estimate
Estimated hold end 2019-06-15. 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 2010-11-10) on 2019-04-15 and reserved on 2019-04-17. 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 2019-06-15. This does not confirm availability.

No transfer record matches. ARIN's statistics show it not issued on 2010-11-09 and assigned (dated 2010-11-10) on 2010-11-11. (Until 2013-03-05, ARIN's statistics list only what's issued.) 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.
