About this ASN.
AS1231’s operator and registered organization are unknown from the supplied evidence, and it announced no IPv4 or IPv6 prefixes in the combined Route Views observation at 2026-11-03 14:00 UTC. That snapshot covered route-views2 and route-views6 together; it does not establish that the ASN is inactive or unused at other times or in other networks.
IANA lists AS1231 in the resource block 1–1876 as assigned by ARIN. This identifies the allocating regional registry, not an individual assignment record, organization, country, or present-day operator. The available material supplies no first-party evidence linking an organization, product, or website to this ASN.
For identification, compare the ASN and observation time with a newer routing snapshot and check the relevant registry assignment record or operator’s own documentation. Treat any later route as evidence of an observed announcement at that time; investigate its origin and path separately. The current zero counts are useful for snapshot triage, but cannot establish ownership, safety, or historical use.
