Summary
- // analyst note

About this ASN.
AS1528 is an autonomous system number assigned by ARIN, according to the IANA AS-number registry. The supplied evidence does not identify an operator, organization, country, network type, or website for this ASN. Registry assignment alone does not establish who operates it or whether it is deployed.
In the combined Route Views observation from route-views2 and route-views6 at 2026-11-03 14:00 UTC, no IPv4 or IPv6 prefixes, address space, or AS_PATH neighbours were observed for AS1528. These are snapshot results across the named collectors; they do not establish that the ASN is inactive or that it has no routing elsewhere or at other times.
For identification, compare the ASN against a later routing snapshot and check for a matching first-party network or registry record before attributing it to an organization. Treat any future AS_PATH adjacency as an observed route relationship only, not proof of a commercial peer, upstream, or customer relationship. The supplied evidence does not support a safety or threat assessment.
- Routing observation
- Zero IPv4 prefixes, zero IPv6 prefixes, and zero observed AS_PATH neighbours in the combined snapshot at 2026-11-03 14:00 UTC across route-views2 and route-views6.
- Security context
- Unknown; the supplied evidence contains no security findings.
- Triage
- Do not infer inactivity or safety from this single snapshot. Check later observations and seek first-party evidence before assigning an operator.
