Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it reserved on 2024-02-27 and assigned (dated 2024-02-28) on 2024-02-29. The tracker saw this range released from hold on 2024-02-27 (AS394837), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2024-02-27: Remove AS394837), so the before-and-after statistics may include it.

ARIN's statistics now list it as 'available'; reissue not confirmed
ARIN's statistics show it reserved on 2024-02-26 and available on 2024-02-28. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. The tracker saw it removed from registration on 2023-06-12, 260 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2024-02-28: Add AS394837), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2023-12-12. 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 2016-01-21) on 2023-06-11 and reserved on 2023-06-13. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed ASNs for 6 calendar months before reissuing them, so the estimated hold end is 2023-12-12. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2016-01-20 and assigned (dated 2016-01-21) on 2016-01-22. 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.
