Summary

// analyst note
The zero counts and empty AS_PATH neighbour sample describe the combined observation from route-views2 and route-views6 at 2026-11-01T00:00:00.000Z only; they do not establish inactivity or deployment status.

About this ASN.

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

AS1040 is an ASN whose allocating RIR is listed as ARIN; its operator and live deployment status are unknown. A combined Route Views snapshot observed zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero AS_PATH neighbours for AS1040 at 2026-11-01 00:00 UTC. This describes those observations only; it does not establish that the ASN is dormant, inactive, unassigned to an organization, or safe or unsafe.

IANA lists AS1040 within resource range 1–1876 as “Assigned by ARIN,” identifying the allocating registry but not an individual assignment record. Its operator, country, network type, website, and organizational status are unknown. In the combined Route Views snapshot from collectors route-views2 and route-views6 at 2026-11-01 00:00 UTC, AS1040 had no observed IPv4 or IPv6 prefixes, estimated IPv4 addresses, or AS_PATH neighbours. The neighbour count measures observed AS_PATH adjacencies; it does not identify commercial peers or upstream providers.

For identification, compare the ASN with an authoritative registry assignment record and seek first-party documentation that explicitly links an organization to AS1040. For routing triage, check additional dated routing snapshots and relevant vantage points before drawing conclusions about announcement activity. The observed zero counts and empty neighbour sample are useful as a baseline for this combined two-collector snapshot, not as proof of absence beyond it.

Identity
The allocating RIR is ARIN; the ASN’s operator is unknown.
Routing snapshot
At 2026-11-01 00:00 UTC, the combined Route Views observation from route-views2 and route-views6 contained zero IPv4 and IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours.
Triage
This single snapshot does not establish whether AS1040 is dormant, inactive, or deployed elsewhere.
