About this ASN.

Updated  ·  Confidence: Low  ·  4 sources  ·  How this page is checked

AS1491 is an ASN whose registered organization and operational identity are Unknown; the combined routing observation shows no announced prefixes at the snapshot time. IANA lists AS1491 within the resource block 1–1876 as assigned by ARIN. This identifies the allocating regional registry for the block, not an individual assignment record or the ASN’s operator.

In the combined Route Views observation from route-views2 and route-views6 at 2026-11-03 14:00 UTC, AS1491 had zero IPv4 prefixes, zero IPv6 prefixes, and zero represented IPv4 addresses. No AS_PATH neighbours were observed. These counts describe that snapshot only; they do not establish whether the ASN is inactive, who controls it, or whether it has ever been used.

For identification, compare the ASN with the specific IP address, prefix, timestamp, and routing context involved in an investigation. A zero-prefix snapshot cannot attribute an address or activity to AS1491. Check additional dated routing observations and authoritative assignment records before associating it with an organization or location. The supplied evidence does not establish a country, network type, website, or security status.

Identity
AS1491’s operator and registered organization are Unknown from the supplied evidence.
Routing snapshot
Zero IPv4 and IPv6 prefixes were observed in the combined Route Views data at 2026-11-03 14:00 UTC.
Triage
No AS_PATH neighbours were observed in that snapshot; this does not establish inactivity or security status.
