No transfer record matches. ARIN's statistics show it reserved on 2025-12-14 and allocated (dated 2025-12-15) on 2025-12-16. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

ARIN's transfer log records a transfer from INV Performance Surfaces, LLC (ARIN) to Allnodes Inc (ARIN) on 2025-12-15 20:24 UTC. ARIN-Issued lists it as "Add" because the registration changed hands; it is not a new allocation from ARIN.

ARIN's statistics show it reserved on 2025-12-14 and assigned (dated 2025-12-15) on 2025-12-16. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS11150. The issuance is explained on that line.

ARIN's transfer log records a merger, acquisition or reorganization from Impulse Internet Services (ARIN) to Impulse Advanced Communications, LLC (ARIN) on 2025-12-15 16:48 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.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2026-06-15. 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 2016-12-22) on 2025-12-14 and reserved on 2025-12-16. 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 2026-06-15. This does not confirm availability. Since mid-2024, ARIN has released many ASNs within two months, before the 6 calendar months were up, so the release can come sooner.

ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2026-02-13. This does not confirm availability.
