About this ASN.

Updated  ·  Confidence: Low  ·  3 sources  ·  How this page is checked

AS1574 is an autonomous system number assigned by ARIN. In the combined Route Views snapshot observed at 2026-11-06 20:00 UTC, it had zero IPv4 prefixes, zero IPv6 prefixes, and zero estimated IPv4 addresses across route-views2 and route-views6. This snapshot does not identify an operator or establish whether the ASN is currently deployed.

The combined observation also records zero AS_PATH neighbours. That means no neighbours were observed for AS1574 in these collectors at this timestamp; it does not establish commercial peering relationships, upstreams, inactivity, or a lack of visibility elsewhere. The observation is limited to the stated time and collectors.

For investigation, compare observations from additional dates and routing collectors before drawing conclusions about announcement history. If a candidate network or organization is identified independently, verify its explicit connection to AS1574 using first-party evidence. Treat the ARIN entry as the allocating RIR designation, not as an individual assignment record or proof of ownership, location, traffic, or security status.

Routing snapshot
Zero IPv4 and IPv6 prefixes and zero AS_PATH neighbours were observed in the combined Route Views observation at 2026-11-06 20:00 UTC.
Triage
Operator identity and deployment status are Unknown; this single snapshot does not establish whether AS1574 is active elsewhere or at another time.
Identification
Compare other dates and collectors, then seek first-party evidence explicitly linking any candidate organization to AS1574.
