About this ASN.

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

AS1391 is an ASN whose operator and registered name are unknown from the supplied evidence; the combined RouteViews observation shows zero IPv4 prefixes, zero IPv6 prefixes, and zero observed AS_PATH neighbours. This describes the snapshot at 2026-11-03 14:00 UTC across route-views2 and route-views6, not the ASN’s status at other times.

IANA identifies ASN 1391 as part of resource range 1–1876, assigned by ARIN. This identifies the allocating regional registry for that block; it does not establish an individual assignment, current operator, country, or deployment. No first-party organization evidence or product information was supplied to connect an entity to AS1391.

For identification, compare a current routing view and registry records that explicitly name AS1391, then verify any candidate operator through its own published material. If investigating a related address or service, check its specific prefix and contemporaneous routing data rather than inferring ownership or safety from this ASN snapshot. The zero counts here mean no routes or neighbours were observed within the stated combined snapshot; they do not show that the ASN is dormant or inactive.

Routing snapshot
Zero IPv4 prefixes, zero IPv6 prefixes, and zero observed AS_PATH neighbours in the combined observation at 2026-11-03 14:00 UTC across route-views2 and route-views6.
Identity
Operator, registered name, country, and network type are unknown from the supplied evidence.
Triage
Treat the zero counts as snapshot-specific; they do not establish inactivity, ownership, deployment, or safety.
