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 |
|---|---|---|---|
| AS21738 | Rozint | Declared | Observed |
| AS41051 | Openfactory GmbH | Declared | Observed |
| AS53356 | Free Range Cloud Hosting Inc. | Declared | Observed |
| AS58057 | Securebit AG | Declared | Observed |
| AS206075 | Hollander & Jacobsen UG (haftungsbeschraenkt) | Declared | not observed |
| AS212895 | Johannes Ernst | not declared | Observed |
| AS37989 | DCS1 Pte. Ltd. | not declared | 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 AS207852 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.
