About this ASN.

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

AS1120 is an ASN with routes visible in a combined Route Views snapshot; its operator and operational purpose are unknown from the supplied evidence. On 2026-11-03 at 14:00 UTC, the route-views2 and route-views6 collectors jointly observed 2 IPv4 prefixes, representing an estimated 512 IPv4 addresses, and 2 IPv6 prefixes. These figures describe that timestamp and those collectors only.

The same combined observation recorded 7 AS_PATH neighbours: AS1853, AS3303, AS6939, AS9002, AS14650, AS31529, and AS57463. These are path adjacencies, not verified peering sessions or evidence of provider, customer, or upstream relationships. Routing data alone does not identify who operates AS1120 or where it is based.

IANA places AS1120 in the resource range 1–1876, described as assigned by ARIN. This identifies the allocating RIR for the block; it does not establish an individual assignment record, current ownership, or deployment. For investigation, compare later snapshots from multiple collectors to assess whether these announcements persist, and inspect the originated prefixes and their registry records before attributing them to an organization. Do not infer inactivity or safety from this limited observation.
