About this ASN.

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

AS1311 is an ASN with 10 IPv4 prefixes observed in a combined Route Views snapshot; its operator and deployment identity are unknown from the supplied evidence. The observation was taken at 2026-11-03 14:00 UTC by route-views2 and route-views6. It included an estimated 2,304 IPv4 addresses and no IPv6 prefixes. These counts describe that snapshot only, not present-day activity or the ASN’s registration status.

The combined observation records four AS_PATH neighbor numbers: AS174, AS3356, AS6461, and AS32787. These are observed path adjacencies; they do not establish direct commercial peering, upstream, customer, or provider relationships. For an operational investigation, compare later routing snapshots and inspect the paths and origin details for the individual prefixes before drawing conclusions about reachability or control.

IANA places ASN 1311 in the resource range 1–1876 and identifies ARIN as the allocating RIR. This is block-level registry information, not an individual assignment record, and it does not identify an organization, country, product, or website. The supplied material contains no first-party evidence linking an operator to AS1311 and no security findings. Treat identity and safety as undetermined; use independently verified registration and operator evidence before making attribution claims.
