AS61438 ASPA Check - IP IT Ip It Consult
PublishedIP-IT-AS ip-it consult GmbH🇦🇹 - ASPA check for AS61438: the upstream transit providers AS61438 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS61438 as their provider. Routers that validate ASPA use these records to detect route leaks in BGP paths.
How to read this ASPA check
The 6 providers below are the only networks allowed to appear directly above AS61438 in an AS-path. If AS61438 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.
