About this ASN.

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

AS1138 is an ASN in the IANA range assigned by ARIN; its registered organization and operational status are Unknown. In the combined Route Views observation at 2026-11-03 14:00 UTC, no IPv4 or IPv6 prefixes were observed, and the projection records zero AS_PATH neighbours. This is a snapshot result, not evidence that the ASN is dormant or inactive.

The observation combines route-views2 and route-views6. It records zero IPv4 address estimate alongside the zero prefix counts. The empty neighbour sample means no AS_PATH adjacency was captured for this ASN in that combined observation; it does not establish anything about commercial relationships or upstreams.

For identification, treat AS1138 as unresolved from these materials: the IANA block identifies an allocating RIR, not an individual assignment or operator. To investigate a particular network claim, compare a timestamped routing view with authoritative registry or operator documentation that explicitly connects the organization to AS1138. Do not infer deployment, traffic, safety, or security status from this snapshot.

Observed routing
Zero IPv4 prefixes, IPv6 prefixes, and AS_PATH neighbours in the combined Route Views observation at 2026-11-03 14:00 UTC, using route-views2 and route-views6.
Triage
Organization and operational status are Unknown; the snapshot alone does not establish dormancy or activity.
Identification
Verify any claimed operator through authoritative assignment or operator documentation explicitly tied to AS1138.
