About this ASN.
AS1538 had no IPv4 or IPv6 prefixes, no address estimate, and no AS_PATH neighbours in the combined Route Views observation at 2026-11-06 20:00 UTC. The snapshot combines route-views2 and route-views6; these zero counts describe only that observation and do not establish that the ASN is inactive or unused. The available evidence does not identify an operator, country, network type, or website.
IANA lists AS1538 within the resource range 1–1876 as assigned by ARIN. This identifies the allocating RIR for the block, not a specific assignment record or deployed organization. For triage, treat the ASN as unidentified and absent from this sampled routing view. If investigating a related address or incident, compare the address’s current route and origin ASN with additional dated routing observations, then seek an authoritative organization record explicitly linking the organization to AS1538.
