About this ASN.

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

AS1631 has no identified operator in the supplied evidence; a combined Route Views snapshot observed five IPv4 prefixes and no IPv6 prefixes. This establishes that routes were visible at the stated observation time, not who operates the ASN or whether it is currently active beyond that snapshot.

The snapshot, observed at 2026-11-06 20:00 UTC, combines route-views2 and route-views6 data. It covers 1,280 IPv4 addresses and records three AS_PATH neighbours: AS15830, AS17378, and AS36086. These adjacencies do not establish verified peers or commercial relationships.

IANA identifies the ASN as assigned by ARIN within the 1–1876 resource block; this does not identify an individual assignee. For triage, compare the ASN and its announced prefixes with the exact address and event time under investigation, then corroborate any attribution using independent registration or operator evidence. Do not infer ownership, location, legitimacy, or threat activity from these routing observations.

Identity
Operator and organization are unknown from the supplied evidence.
Routing
Five IPv4 prefixes and zero IPv6 prefixes observed in the combined snapshot at 2026-11-06 20:00 UTC.
Triage
Three observed AS_PATH neighbours are routing adjacencies, not confirmed peers or providers.
