Autonomous system detail

AS905

Not announced

No prefixes for this AS number were observed in the RouteViews RIB.

Summary

// analyst note
Dormant autonomous system: RouteViews observed zero IPv4 and zero IPv6 prefixes and zero neighboring ASNs at its 2026-08-20 snapshot, a genuine none-observed result rather than a lookup failure. The CAIDA AS Relationships dataset (2026-08-01) classifies no relationship touching AS905 in either direction. RIR is ARIN, from the IANA AS Number registry range 1-1876 ("Assigned by ARIN"). No operator-published material identifies AS905 as of a September 2026 search, so operator, country, network type, and organizational identity stay Unknown; do not promote them out of Unknown on the strength of an IP-intelligence directory or a mirror of RIR data.

About this ASN.

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

AS905 is a dormant autonomous system that originates no prefixes today, and no permitted source identifies its operator. As observed by the RouteViews route collector at its 2026-08-20 snapshot, the ASN announced zero IPv4 and zero IPv6 prefixes, with zero neighboring ASNs visible to the collector — a genuine none-observed result, not a lookup failure.

The IANA AS Number registry places AS905 in the 1-1876 range, recorded as "Assigned by ARIN," making ARIN its administering RIR. The CAIDA AS Relationships dataset (2026-08-01) classifies no relationship touching AS905 in either direction — an absence of classification, not confirmation of zero neighbours.

No operator-published material identifies AS905 as of a September 2026 search, so operator, organization name, country, network type, and website all stay Unknown.

No notable public abuse or threat-intelligence signal names AS905 as of a September 2026 search. Given the ASN shows no announced address space in the current RouteViews snapshot, it is a low-salience target for IP-level abuse feeds, which key off announced prefixes — a fact consistent with, but not proof of, a clean history.

Routing exposure
Zero prefixes announced at the RouteViews 2026-08-20 snapshot means no live IP-level abuse surface is attributable to this ASN at that instant.
CVE / malware
No CVE, malware, or botnet command-and-control association naming AS905 found as of a September 2026 search.
Operator
Unknown — no operator-published material identifies AS905 as of a September 2026 search [Unknown]
