About this ASN.

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

AS1566 is an ASN whose operator and country are unknown from the supplied evidence; it had no IPv4 or IPv6 prefixes observed in the combined Route Views snapshot at 2026-11-06 20:00 UTC. This is a snapshot result, not evidence that the ASN is dormant, inactive, or unassigned. The observation combines route-views2 and route-views6 data, so the aggregate counts should not be read as separate measurements from each collector.

The IANA AS-number registry places AS1566 in the resource range 1–1876 and identifies ARIN as the allocating RIR. That block-level entry does not identify an individual assignment, organization, location, or present-day operator. No supplied first-party material links an operator, product, website, or network type to this ASN.

For triage, treat the zero prefix and peer counts as absence from this particular combined observation only. If investigating a specific address or claimed organization, check its current route visibility and authoritative registry records independently, then compare any observed origin ASN with the claim. The empty AS_PATH-neighbour sample provides no neighbour to assess; it does not establish a peering policy, upstream relationship, or security status. No reputation or security findings are supplied.

Routing snapshot
Zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours in the combined route-views2 and route-views6 observation at 2026-11-06 20:00 UTC.
Triage
These zero counts describe one snapshot and do not establish dormancy, inactivity, assignment status, or safety.
Security context
No reputation score or security finding is supplied; investigate any claimed IP or organization using current routing and authoritative registry data.
