About this ASN.

Updated  ·  Confidence: Low  ·  4 sources  ·  How this page is checked

AS1154 is an ASN whose operator and registered organization are unknown from the supplied evidence; the combined routing snapshot observed zero IPv4 and zero IPv6 prefixes. This is a snapshot result, not proof that the ASN is inactive or unallocated.

At 2026-11-03 14:00 UTC, Route Views collectors route-views2 and route-views6 jointly observed zero prefixes, zero IPv4 addresses represented by those prefixes, and zero AS_PATH neighbours for AS1154. No neighbours were sampled. These totals describe the combined observation and are not separate counts for each collector.

The IANA AS-number listing places AS1154 in the 1-1876 resource block and identifies ARIN as the allocating RIR. That block-level record does not establish an individual assignment, operator, country, or network purpose. The supplied evidence contains no first-party organization profile or documented products linked to this ASN.

For identification, compare a fresh routing observation with registry records that explicitly associate AS1154 with an organization, then corroborate that association through the organization’s own published materials. Treat any newly observed routes as evidence of announcement at that time; inspect their origin paths and route validity separately before drawing conclusions about operational role or safety.

Identity
Operator and organization are unknown from the supplied evidence.
Observed routing
Zero IPv4 prefixes, zero IPv6 prefixes, and zero AS_PATH neighbours in the combined Route Views observation at 2026-11-03 14:00 UTC.
Interpretation
The snapshot does not establish inactivity, assignment, ownership, or safety.
