About this ASN.

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

AS1151 has no IPv4 or IPv6 prefixes observed in the combined Route Views snapshot dated 2026-11-03 14:00 UTC; its operator and deployment status are unknown. This single observation combines route-views2 and route-views6, so it describes visibility at that time across those collectors, not the ASN’s current activity or identity.

The same snapshot records zero estimated IPv4 addresses, zero observed AS_PATH neighbours, and no neighbour sample. These observations do not establish that the ASN is inactive, unassigned, or unused. IANA identifies AS1151 within the resource range 1–1876 as assigned by ARIN; that identifies the allocating RIR and does not provide an individual assignment record or operator.

For identification, compare this snapshot with current routing data and registry records that explicitly connect an organization to AS1151. If investigating a route or service attributed to this ASN, verify the observed announcement and its origin in the relevant time window, then corroborate the organization through a first-party source. The supplied evidence does not establish products, location, security status, or legitimacy.

Routing visibility
No IPv4 or IPv6 prefixes were observed in the combined 2026-11-03 14:00 UTC snapshot from route-views2 and route-views6.
Triage
Zero observed prefixes and neighbours in this snapshot do not establish present-day inactivity or security status.
Identification
Confirm any attribution with time-matched routing data and a first-party record explicitly linking an organization to AS1151.
