AS1397
No prefixes for this AS number were observed in the RouteViews RIB.
Summary
- // analyst note
- IANA identifies AS1397 in resource range 1–1876 as assigned by ARIN; this is block-level RIR information, not an individual assignment record.
- // security note
- No IPv4 or IPv6 prefixes or AS_PATH neighbours were observed in the combined RouteViews snapshot at 2026-11-03T14:00:00Z across route-views2 and route-views6.
About this ASN.
AS1397 is an ASN whose operator and registered organization are unknown from the supplied evidence; no IPv4 or IPv6 prefixes were observed in the combined RouteViews snapshot at 2026-11-03 14:00 UTC. The zero counts describe that observation across route-views2 and route-views6 only. They do not establish that the ASN is dormant, inactive, or unused.
IANA identifies AS1397 within the resource range 1–1876 as assigned by ARIN. This identifies the allocating RIR for the block, not an individual assignment record or the ASN’s operator, location, or present deployment. No first-party organization, product, or history evidence was supplied to connect AS1397 to an entity.
For investigation, compare this snapshot with later routing observations and consult authoritative registry records for an individual assignment. If AS1397 appears in a future AS_PATH, inspect the surrounding path and advertised prefixes; adjacency alone would not verify a commercial peer, upstream, or customer relationship. Treat identity and safety as undetermined on this evidence.
