About this ASN.

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

AS1542 is an ASN with an unknown operator; in the combined Route Views snapshot at 2026-11-06 20:00 UTC, one IPv6 prefix and no IPv4 prefixes were observed. This is a snapshot status, not evidence of sustained activity, deployment, ownership, or safety. IANA identifies the ASN as part of resource block 1–1876, assigned by ARIN; that block-level designation does not identify an individual organization or assignment record.

The combined observation across route-views2 and route-views6 contains one observed AS_PATH neighbour, AS306. Adjacency alone does not establish a commercial peer, upstream, customer, or provider relationship. The snapshot reports an IPv4 address estimate of zero because it observed no IPv4 prefixes. It does not establish that the ASN has never announced IPv4 space or is inactive at other times.

For identification, compare the ASN and any candidate IPv6 prefix with dated routing records and registry records that explicitly bind an organization to AS1542. Treat AS306 only as a lead for examining the observed path, not as proof of a business relationship. Use current routing observations to assess present reachability, and seek first-party documentation before attributing an operator, products, geography, or purpose. The supplied evidence contains no such identity or security information.

Identity
Operator and organizational identity are unknown from the supplied evidence.
Routing snapshot
Combined observation at 2026-11-06 20:00 UTC across route-views2 and route-views6 shows one IPv6 prefix and zero IPv4 prefixes.
Observed adjacency
AS306 appears as the sole sampled AS_PATH neighbour; this does not verify a peering or provider relationship.
Triage
Treat these counts as a single dated routing snapshot; they do not establish activity at other times, ownership, or safety.
