About this ASN.

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

AS1142 is in IANA’s ARIN-assigned 1–1876 ASN block. In the combined Route Views observation at 2026-11-03 14:00 UTC, it had zero IPv4 and IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours. Its operator and deployment status are unknown.

The routing counts combine route-views2 and route-views6; they are not separate counts for each collector. The empty observation describes only those collectors at that timestamp. It does not establish that AS1142 is inactive, unassigned to an organization, or absent from other routing data.

For identification, treat the ARIN label as the allocating RIR only, not as an operator or individual assignment record. If investigating a specific network, compare its claimed ASN with a dated routing snapshot and an authoritative organization-to-ASN record. Do not infer an upstream, customer relationship, or security status from this observation: it contains no observed neighbours and supplies no security findings.

Identity
Operator and deployment status are unknown from the supplied evidence.
Triage
