About this ASN.

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

AS1672 had no IPv4 or IPv6 prefixes observed in the combined Route Views snapshot at 2026-11-06 20:00 UTC. The snapshot combines route-views2 and route-views6; it records zero IPv4 addresses estimated, zero AS_PATH neighbours, and no neighbour samples. This describes that observation only. It does not establish whether the ASN is currently assigned to an operator, deployed, inactive, or used for any particular purpose.

IANA lists AS1672 within the resource range 1–1876 as assigned by ARIN, identifying ARIN as the allocating RIR. The supplied evidence does not identify an operator, country, network type, official website, or organization status. For investigation, compare a later routing snapshot and consult authoritative registry records for any operator attribution. If examining an address or incident, verify its specific prefix and timestamp independently; the zero-route observation alone cannot connect AS1672 to that activity or establish safety.

Routing observation
Zero IPv4 and IPv6 prefixes and zero observed AS_PATH neighbours in the combined snapshot at 2026-11-06 20:00 UTC, using route-views2 and route-views6.
Triage
The snapshot provides no observed routes to use for prefix-based attribution; identify and validate any specific address, prefix, and event time independently.
Identity
Operator, country, deployment, and safety are unknown from the supplied evidence.
