AS212341 ASPA Check - CSN Datacenters Stephan Rakowski, Trading CSN Solutions
PublishedCSN-Datacenters Stephan Rakowski, trading as CSN-Solutions GmbH🇩🇪 - ASPA check for AS212341: the upstream transit providers AS212341 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS212341 as their provider. Routers that validate ASPA use these records to detect route leaks in BGP paths.
How to read this ASPA check
The 7 providers below are the only networks allowed to appear directly above AS212341 in an AS-path. If AS212341 uses a transit provider that is missing from this list, routers that enforce ASPA treat its routes through that provider as invalid, so the list should include every current and backup transit provider. Peers do not belong in it.
