About this ASN.

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

AS1381’s operator and purpose are unknown from the supplied evidence; it announced zero IPv4 and zero IPv6 prefixes in the combined Route Views snapshot observed at 2026-11-03 14:00 UTC. This is a time-bounded routing observation, not evidence that the ASN is dormant, inactive, or currently unassigned.

The IANA ASN registry identifies AS1381 within the block 1–1876 as “Assigned by ARIN.” This identifies the allocating regional internet registry for the block; it does not establish an individual assignment record, operator, country, or deployment.

Across the route-views2 and route-views6 collectors combined, the snapshot recorded zero prefixes, an IPv4 address estimate of zero, and zero observed AS_PATH neighbours. No neighbour sample is present. These counts do not describe either collector separately, and AS_PATH adjacency would not by itself establish a commercial peer or upstream relationship.

For identification, compare the ASN with a fresh routing observation and seek a first-party registry or organizational record that explicitly connects an operator to AS1381. Treat any later announcement as evidence for its observed time and vantage point; the supplied snapshot alone cannot establish present-day routing or explain the absence of routes.
