AS199938 ASPA Check - NETZWERGE

NETZWERGE Netzwerge GmbH🇩🇪 - ASPA check for AS199938: the upstream transit providers AS199938 has authorized in its RPKI Autonomous System Provider Authorization (ASPA) object, and the networks that list AS199938 as their provider. Routers that validate ASPA use these records to detect route leaks in BGP paths.

AS199938 has not published its own ASPA object, but 1 ASN lists it as an authorized upstream provider.

About ASPA - what it is and why AS199938 should publish one

ASPA (Autonomous System Provider Authorization) is a cryptographically signed RPKI object specified in the IETF draft-ietf-sidrops-aspa-profile that lets an AS declare which upstream networks are its authorized transit providers. Together with route origin validation (ROV), ASPA enables BGP route leak detection: routers can reject AS-paths in which a network appears as a provider without being authorized. Route leaks are a frequent cause of large routing incidents, and ROV alone cannot detect them because the origin of a leaked route is correct.

AS199938 (NETZWERGE Netzwerge GmbH) has not published an ASPA object. Hops through it are therefore "unknown" to ASPA validation - not invalid, but not protected either. An ASPA object lists every transit provider of the network (or AS0 if it has none) and is created in the RIR's hosted RPKI where ASPA is supported, or in a delegated RPKI setup. For most networks the record is a short list of their upstream ASNs.
