AS28755 ASPA Check - HA VEL TRANSIT Ha Vel Internet S.R.O
PublishedHA-VEL-TRANSIT-AS ha-vel internet s.r.o.🇨🇿 - ASPA check for AS28755: the upstream transit providers AS28755 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS28755 as their provider. Routers that validate ASPA use these records to detect route leaks in BGP paths.
How to read this ASPA check
The provider below is the only network allowed to appear directly above AS28755 in an AS-path. If AS28755 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.
