Summary

// analyst note
Combined Route Views observation from route-views2 and route-views6 at 2026-11-06T20:00:00.000Z: one IPv4 prefix, zero IPv6 prefixes, estimated 256 IPv4 addresses, and one AS_PATH neighbour sampled as AS703. The neighbour is not a verified commercial relationship.

About this ASN.

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

AS1670 has one IPv4 prefix and no IPv6 prefixes observed in the combined Route Views snapshot at 2026-11-06 20:00 UTC. The available evidence does not identify its operator, country, or network type, so its identity and operational purpose remain unknown. The snapshot is a point-in-time routing observation, not a record of ownership or deployment.

The combined observation from route-views2 and route-views6 estimates 256 IPv4 addresses and records one AS_PATH neighbour, AS703. That adjacency does not establish a verified BGP peer, upstream, customer, or provider relationship. No IPv6 prefix was observed in this snapshot; that alone does not show that AS1670 is inactive or lacks IPv6 elsewhere.

For triage, compare the observed IPv4 announcement and its AS path with the route data relevant to the incident and time in question. Treat AS703 only as an observed path neighbour, and seek independent first-party documentation before assigning an operator or purpose. The IANA evidence identifies ARIN as the allocating RIR for the enclosing ASN block; it does not establish an individual assignment or current operator.

Routing exposure
One IPv4 prefix and zero IPv6 prefixes were observed in the combined snapshot at 2026-11-06 20:00 UTC.
Identity
Operator, country, network type, and website are unknown from the supplied evidence.
Triage
AS703 is an observed AS_PATH neighbour only; investigate the relevant announcement and time-specific path before drawing relationship conclusions.
