About this ASN.

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

AS1287 is assigned from the ARIN portion of the IANA AS-number registry; its registrant and operator are unknown, and no routes were observed in the combined snapshot dated 2026-11-03 14:00 UTC. This is a snapshot finding across route-views2 and route-views6, not evidence that the ASN is dormant or inactive. The registry entry does not identify an individual assignment or establish who operates the ASN.

In that combined observation, the projection records zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours. The empty neighbour sample provides no adjacent ASNs to investigate. These counts are not separate measurements attributed to each collector, and AS_PATH adjacency would not by itself establish a commercial peering, upstream, or customer relationship.

For identification, treat AS1287 as unresolved until an operator explicitly links itself to this ASN in first-party documentation or registry records. If assessing a particular connection or log entry, compare its timestamp and announced prefix with a fresh routing observation and the original network record. The supplied evidence establishes registry allocation scope and one routing snapshot only; it does not establish deployment, traffic, location, products, safety, or security findings.

Routing snapshot
Zero IPv4 and IPv6 prefixes observed in the combined route-views2 and route-views6 observation at 2026-11-03 14:00 UTC.
Triage
No routes or AS_PATH neighbours were observed in that snapshot; this alone does not establish inactivity or risk.
Identity
Operator and registrant are unknown from the supplied evidence; the IANA entry identifies ARIN as the allocating RIR.
