- Zero routes and neighbours were observed in the combined snapshot from route-views2 and route-views6 at 2026-11-03 14:00 UTC; this does not establish inactivity or operator identity.
About this ASN.
AS1191 is an autonomous system number in the IANA block marked “Assigned by ARIN.” In the combined Route Views snapshot observed at 2026-11-03 14:00 UTC, it had zero IPv4 prefixes, zero IPv6 prefixes, and zero observed AS_PATH neighbours. This snapshot does not establish who operates the ASN or whether it is deployed elsewhere.
The zero counts describe only the combined observation from route-views2 and route-views6 at that timestamp. They are not separate counts from each collector, and they do not show that the ASN is dormant, inactive, or unavailable on other networks or at other times. No neighbour sample was present in the supplied projection.
For identification, compare the ASN and observation time with the routing view relevant to the network or incident under review, then check later snapshots for announcements or neighbours. Treat any match as a routing observation, not proof of organizational ownership or a commercial relationship. The supplied evidence contains no first-party operator, country, website, product, or security information, so those attributes remain unknown.

- Security context
- No security findings or reputation evidence were supplied; routing absence in this snapshot is not a safety or threat assessment.
- Identification
- Compare the ASN and timestamp against the routing view relevant to an investigation, and check other times before drawing deployment conclusions.
