AS1663
No prefixes for this AS number were observed in the RouteViews RIB.
Summary
- // analyst note
- Combined routing observation from route-views2 and route-views6 at 2026-11-06 20:00 UTC recorded zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours. This single snapshot does not establish inactivity or safety.
About this ASN.
AS1663 is an ASN with an unknown operator; it had no IPv4 or IPv6 prefixes observed in the combined Route Views snapshot at 2026-11-06 20:00 UTC. That snapshot combines route-views2 and route-views6 observations. It does not establish that the ASN is dormant, inactive, or unused outside those collectors and that timestamp.
IANA places AS1663 in the resource block described as “Assigned by ARIN,” identifying ARIN as the allocating RIR. This block-level record does not identify an individual assignment, operator, country, or network purpose. No first-party identity or organizational evidence is supplied, so those details remain unknown.
For triage, treat the zero counts as a snapshot observation rather than a safety or reputation signal. When investigating a specific address or incident, compare its origin and route history at the relevant time, check other collectors and current routing data, and seek an independently verified operator record. The empty observed-neighbour sample provides no basis for inferring upstreams or commercial relationships.
- Identity
- Operator and network purpose are unknown from the supplied evidence.
- Routing snapshot
- Zero IPv4 prefixes, zero IPv6 prefixes, zero estimated IPv4 addresses, and zero observed AS_PATH neighbours in the combined observation at 2026-11-06 20:00 UTC across route-views2 and route-views6.
- Triage
- The snapshot does not establish inactivity, safety, malicious use, or ownership; investigate time-relevant routes and independently verified identity evidence.
