About this ASN.

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

AS1587 is an autonomous system whose registered organization and operational identity are unknown from the supplied records; it had no IPv4 or IPv6 prefixes observed in the combined Route Views snapshot at 2026-11-06 20:00 UTC. The observation combines route-views2 and route-views6. It does not establish whether the ASN is inactive, who operates it, or whether it is safe or legitimate.

The IANA registry data places AS1587 in the resource range 1–1876, described as assigned by ARIN. This identifies the allocating regional registry for the block; it does not establish an individual assignment record, organization, country, or deployment.

For identification, compare a candidate ASN or network claim against dated routing observations and primary registry records. Here, the snapshot reports zero observed peers and an empty AS_PATH-neighbour sample, so it provides no adjacent ASNs to investigate. Treat those zeroes as limited to this timestamp and these collectors; seek first-party documentation explicitly linking an organization to AS1587 before attributing its operation.
