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 |
|---|---|---|---|
| AS34872 | Sarah Rossius trading as Servperso Systems | Declared | Observed |
| AS34927 | iFog GmbH | Declared | Observed |
| AS44103 | The Mastermind Holding B.V. | Declared | Observed |
| AS212895 | Johannes Ernst | Declared | Observed |
| AS199854 | Jens Thies | not declared | Observed |
| AS401753 | BIXCE Inc | 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 AS215561 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.
