No prefixes for this AS number were observed in the RouteViews RIB.

Summary

// analyst note
The supplied evidence does not identify an operator or purpose. Routing counts are a combined observation across both named collectors.
// security note
Zero prefixes and AS_PATH neighbours observed in the combined Route Views snapshot at 2026-11-03T14:00:00Z across route-views2 and route-views6; snapshot absence does not establish inactivity, safety, or malicious use.

About this ASN.

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

AS1398’s operator and purpose are unknown from the supplied evidence. In the combined Route Views snapshot at 2026-11-03 14:00 UTC, it had zero observed IPv4 prefixes, zero IPv6 prefixes, and zero AS_PATH neighbours across route-views2 and route-views6. This describes that snapshot only; it does not establish that the ASN is inactive or unassigned.

IANA identifies AS1398 within resource 1-1876, described as “Assigned by ARIN,” and lists ARIN as the allocating RIR. That registry block entry is not an individual assignment record and does not identify an operator, country, deployment, or service. The supplied material contains no first-party organization evidence to connect an entity to this ASN.

For triage, treat the routing result as an absence from these collectors at this timestamp, not as evidence of safety or malicious use. If investigating a specific address or incident, compare its observed prefix and timestamp against other routing snapshots and corroborate ownership through first-party documentation or registry records. The supplied snapshot offers no AS_PATH neighbours to investigate further.
