About this ASN.

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

AS1057 is an ASN with unknown operator identity and six IPv4 prefixes observed in the combined Route Views snapshot at 2026-11-01 00:00 UTC. The snapshot includes route-views2 and route-views6. It contains no observed IPv6 prefixes. These are routing observations at one timestamp and do not establish who operates the ASN or whether its announcements are safe or harmful.

The projection estimates 1,536 IPv4 addresses and records one AS_PATH neighbor, AS3356. That adjacency does not establish a commercial peering or upstream relationship. For identification, compare a specific prefix and its origin against the relevant routing data and registry records, then check later observations for persistence. Do not infer an operator, country, deployment, traffic prevalence, or security status from these counts.

The IANA data identifies ARIN as the allocating regional registry for the encompassing ASN block; it is not an individual assignment record for AS1057.

Identity
Operator and network identity are Unknown from the supplied evidence.
Observed routing
Six IPv4 prefixes and zero IPv6 prefixes in the combined observation at 2026-11-01 00:00 UTC.
Triage
One AS_PATH neighbor, AS3356; this does not verify a peer or upstream relationship.
Registry
IANA lists the encompassing block as assigned by ARIN; this does not identify an individual assignee.

Who it talks to.

1 observed neighbour
// Notable connections1 of 1 observed

Neighbours observed by RouteViews at 2026-11-06, lowest ASN first. Relationships are inferences from the CAIDA AS Relationships Dataset, 2026-08-01, and establish no commercial arrangement; a dash means the inference did not resolve.
