About this ASN.

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

AS1172 is an ASN with an unknown operator and identity; the combined RouteViews snapshot observed no announced prefixes, so its live-routing status in that snapshot is no routes observed. This does not establish that the ASN is dormant or inactive.

The IANA AS-number block lists AS1172 in the 1–1876 resource as assigned by ARIN. This identifies the allocating RIR for the block, but does not establish an individual assignment, operator, country, or present-day use.

For 2026-11-03 14:00 UTC, the combined observation from route-views2 and route-views6 recorded zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours. These are snapshot results across the two named collectors, not separate per-collector counts. No neighbours were available to sample.

For identification, compare a candidate ASN or prefix against registry records and later routing snapshots, and seek first-party documentation that explicitly connects the ASN to an organization. Treat this snapshot as evidence about visibility at its stated time and scope only; it cannot establish ownership, deployment, traffic prevalence, safety, or security history.

Identity
Operator and organization are Unknown from the supplied evidence.
Routing snapshot
At 2026-11-03 14:00 UTC, the combined route-views2 and route-views6 observation recorded zero IPv4 and IPv6 prefixes and zero AS_PATH neighbours.
Triage
No routes were observed in this snapshot; this does not establish inactivity or a security finding.
Registry
IANA places AS1172 in the 1–1876 block assigned by ARIN; this does not identify an individual assignee.
