AS1653
No prefixes for this AS number were observed in the RouteViews RIB.
Summary
- // analyst note
- Routing counts are combined observations across route-views2 and route-views6 at 2026-11-06T20:00:00.000Z. Sampled AS_PATH neighbours are not verified peers or commercial relationships.
- // security note
- SUNET CERT’s profile describes incident coordination and assistance for SUNET customers; it does not establish that a particular prefix or incident belongs to AS1653.
About this ASN.
AS1653 had 60 IPv4 prefixes and 2 IPv6 prefixes in the combined Route Views snapshot observed at 2026-11-06 20:00 UTC by route-views2 and route-views6. The projection estimates 618,240 IPv4 addresses and records 36 AS_PATH neighbours. These are snapshot observations; they do not establish the ASN’s operator, location, legitimacy, or commercial relationships.
IANA places AS1653 in resource block 1–1876, assigned by ARIN. This identifies the block’s allocating RIR, not the holder of an individual ASN assignment. The supplied SUNET CERT profile lists AS1653 among the AS numbers corresponding to SUNET-connected customers and describes SUNET CERT as a SUNET network service. That evidence gives useful historical network context, but does not identify AS1653’s operator.
For investigation, compare the ASN’s currently visible routes and origin details with the relevant registry records, then check whether the observed prefixes match the specific service or organization under review. Treat the sampled AS_PATH neighbours as routing context only. SUNET CERT’s profile describes incident coordination and assistance for SUNET customers, so it may help direct security triage when SUNET constituency is independently established; the profile alone does not show that a particular incident or prefix belongs to AS1653.
