About this ASN.

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

AS1540 is an autonomous system whose operator and registered name are not established by the supplied evidence. A combined Route Views observation at 2026-11-06 20:00 UTC recorded 2,163 IPv4 prefixes and 64 IPv6 prefixes. This is a live-routing observation for that timestamp and the named collectors, not proof of ownership, legitimacy, or deployment beyond the observed routes.

The same snapshot estimates 7,824,384 IPv4 addresses and records a peer count of 9. The sampled AS_PATH neighbours are AS153, AS306, AS367, AS588, AS1493, AS1554, AS6006, AS27064, and AS27065. These are observed path adjacencies; the data does not establish direct commercial peering, upstream, or customer relationships. The counts are combined across route-views2 and route-views6, not separate measurements attributed to each collector.

For identification, compare the ASN and the relevant announced prefixes against the operator’s own routing announcements and registry records, then check whether the paths appear in more recent and geographically diverse observations. Investigate any specific address or prefix separately before attributing it to an organization or service. The IANA evidence identifies ARIN as the allocating RIR for the ASN block, but does not supply an individual assignment record, operator, country, or website.

Triage
Use the ASN and specific observed prefixes as investigation pivots, and verify any attribution against current routing and first-party records.
