AS1183
No prefixes for this AS number were observed in the RouteViews RIB.
Summary
- // analyst note
- No IPv4 or IPv6 prefixes or AS_PATH neighbours were observed in the combined Route Views snapshot from route-views2 and route-views6 at 2026-11-03T14:00:00.000Z; this single observation does not establish inactivity, ownership, deployment, or safety.
About this ASN.
AS1183 is an ASN whose operator and registered name are unknown from the supplied evidence; the combined Route Views snapshot observed no announced prefixes or AS_PATH neighbours. This describes one routing observation, not whether the ASN is inactive or who controls it.
At 2026-11-03 14:00 UTC, the combined observation from route-views2 and route-views6 contained zero IPv4 prefixes, zero IPv6 prefixes, and zero estimated IPv4 addresses for AS1183. It also contained zero observed neighbours. The snapshot does not establish allocation to a particular organization, deployment, traffic prevalence, or safety.
For triage, compare observations from additional times and collectors, then check any candidate organization against authoritative first-party records that explicitly associate it with AS1183. If investigating a specific IP address, verify its currently visible prefix and origin separately; this snapshot offers no route or neighbour to use as an attribution lead.
