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 |
|---|---|---|---|
| AS2027 | MilkyWan Association | Declared | Observed |
| AS6939 | Hurricane Electric LLC | Declared | not observed |
| AS24381 | BGP.Exchange | Declared | not observed |
| AS35661 | VIRTUA SYSTEMS SAS | Declared | not observed |
| AS35708 | 4b42 UG | Declared | not observed |
| AS41051 | Openfactory GmbH | Declared | not observed |
| AS51706 | France IX Services SASU | Declared | not observed |
| AS209533 | iFog GmbH | Declared | not 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 AS212037 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.
