About this ASN.

Updated  ·  Confidence: Low  ·  4 sources  ·  How this page is checked

AS1559 is an ASN whose operator and registered organization are Unknown; a combined Route Views observation recorded three IPv4 prefixes and no IPv6 prefixes at 2026-11-06 20:00 UTC. The observation combines route-views2 and route-views6 data. It estimates 66,816 IPv4 addresses and records one AS_PATH neighbor, AS1554. That adjacency does not establish a commercial peer, upstream, customer, or provider relationship.

IANA places AS1559 in the resource block 1–1876, described as assigned by ARIN. This identifies the allocating RIR for the block, not an individual assignment record or current operator. The routing snapshot is limited to one timestamp and these two collectors, so it does not establish activity outside that view, ownership, location, deployment, or safety.

For identification, compare the observed prefixes and paths with a separately verified registry record and additional dated routing observations; investigate AS1554 as a path adjacency only, without assuming a business relationship.

Routing snapshot
Three IPv4 prefixes and zero IPv6 prefixes observed in the combined route-views2 and route-views6 data at 2026-11-06 20:00 UTC.
Identity
The operator and organization are Unknown from the supplied evidence.
Triage
Treat AS1554 only as an observed AS_PATH neighbor; investigate prefixes and paths against separately verified records before attributing them.
