About this ASN.

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

AS1291 is an autonomous system whose operator and purpose are not identified by the supplied evidence. In the combined RouteViews observation at 2026-11-03 14:00 UTC, neither IPv4 nor IPv6 prefixes were observed, and no AS_PATH neighbours were recorded. This is a snapshot finding from route-views2 and route-views6; it does not establish that the ASN is dormant or inactive.

IANA lists AS1291 within the resource range 1–1876 as assigned by ARIN. This identifies the allocating regional internet registry for the block, not an individual assignment record, current holder, country, or operating organization. No first-party material links a named operator, product, or website to this ASN, so its identity and network role remain unknown.

For investigation, compare additional dated routing snapshots and authoritative registry records before drawing conclusions about present use or assignment. If a candidate organization is found, seek first-party documentation that explicitly connects it to AS1291. Do not treat the zero counts as evidence about safety, legitimacy, traffic, or malicious activity; none of those properties is established by the supplied routing and registry observations.
