AS201011 CORE-BACKBONE CORE-BACKBONE GMBH GLOBAL NETWORK
Unclassified RIPE
Announcements
What this network originates
Every prefix observed with AS201011 as its origin, checked against RPKI and the IRR. Problems sort first.
RPKI · ROAs
Route origin authorisations
Signed statements by address holders that AS201011 may originate these prefixes, up to the maximum length shown.
ROA-based and RPKI-valid-only prefix lists for routers are on asn.ipinfo.app.
RPKI · ASPA
Declared transit providers
This network has signed an ASPA record naming its transit providers. Each is compared against the upstreams observed in routing paths.
| AS | Network | ASPA | Routing paths |
|---|---|---|---|
| AS33891 | Core-Backbone GmbH | Declared | Observed |
An observed upstream that is not declared is not necessarily a leak: our upstream inference cannot tell a transit provider from a peer seen in the same position. A declared provider that is never observed is usually a backup path.
IRR
Registered route objects
Route objects naming AS201011 as origin, across RADb, the RIR registries, ALTDB and NTTCOM. Objects that are registered but not announced come first: a stale object lets anyone who can spoof this origin through an IRR-built filter.
