ARIN's transfer log records a merger, acquisition or reorganization from RocketNode Inc (ARIN) to SPARKED HOST LLC (ARIN) on 2026-01-20 19:04 UTC. The registration changed hands; it is not a new allocation from ARIN. ARIN-Issued and ARIN's statistics don't show this change; only the transfer log records it.

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it available on 2022-11-27 and assigned (dated 2022-11-28) on 2022-11-29. The tracker saw this range released from hold on 2022-11-23 (AS397283), so it appears to have been issued again from ARIN's pool.

Remove AS397283
Inventory
ARIN's statistics now list it as 'available'; reissue not confirmed

ARIN's statistics show it reserved on 2022-11-22 and available on 2022-11-24. 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 2022-07-04, 142 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2023-01-04. 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 2019-02-04) on 2022-07-03 and reserved on 2022-07-05. 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 2023-01-04. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2019-02-03 and assigned (dated 2019-02-04) on 2019-02-05. 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.
