About this ASN.

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

AS1656 is an autonomous system number in the IANA block assigned by ARIN; its operator and deployment status are unknown, and no routes were observed in the combined Route Views snapshot at 2026-11-06 20:00 UTC. The observation across route-views2 and route-views6 contained zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours. These counts describe that snapshot only; they do not establish that the ASN is inactive or unused.

For identification, treat AS1656 as an unverified ASN rather than attributing it to an organization based on the number alone. If investigating a route or address associated with it, compare the relevant timestamp and originating AS with additional routing observations and authoritative registry records. The supplied evidence does not identify an operator, country, network type, website, or security status. No neighbour sample was observed, so this snapshot provides no adjacency to investigate further.

Routing observation
Zero IPv4 and IPv6 prefixes were observed in the combined snapshot at 2026-11-06 20:00 UTC across route-views2 and route-views6.
Triage
Operator identity and deployment status are unknown; a zero-count snapshot does not establish inactivity.
Investigation
Compare any reported route and timestamp with other routing snapshots and authoritative registry records before attributing AS1656 to an organization.
