AS1533
No prefixes for this AS number were observed in the RouteViews RIB.
Summary
- // analyst note
- The combined Route Views snapshot from route-views2 and route-views6 observed zero IPv4 and IPv6 prefixes and zero AS_PATH neighbours at 2026-11-03T14:00:00.000Z. This is not evidence of inactivity outside that observation.
About this ASN.
AS1533 is an autonomous system number in the IANA range assigned by ARIN; its operator and live deployment status are unknown. A combined Route Views observation found no announced IPv4 or IPv6 prefixes at 2026-11-03 14:00 UTC across route-views2 and route-views6. This describes that snapshot only, not whether the ASN is dormant or active at other times.
The combined snapshot also recorded zero AS_PATH neighbours and an IPv4 address estimate of zero. No neighbours were available to list. AS_PATH adjacency would not, by itself, establish an upstream, customer, or verified peering relationship. The registry evidence identifies the allocating RIR, not an individual assignment record or operator.
For triage, compare a later routing snapshot and consult authoritative registry records for assignment details before attributing this ASN to an organization or country. If investigating a particular address or route, verify its current origin and announcement at the relevant time; these observations alone cannot establish ownership, location, safety, or security history.
- Routing observation
- Zero IPv4 and IPv6 prefixes and zero AS_PATH neighbours in the combined Route Views snapshot at 2026-11-03 14:00 UTC.
- Registry
- IANA lists the range containing AS1533 as assigned by ARIN; individual assignment and operator are unknown.
- Triage
- Treat the zero counts as limited to the named collectors and observation time; verify current route origin and authoritative assignment records for investigations.
