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 |
|---|---|---|---|
| AS6939 | Hurricane Electric LLC | Declared | Observed |
| AS11967 | Hop179 OU | Declared | Observed |
| AS34549 | meerfarbig GmbH & Co. KG | Declared | Observed |
| AS41051 | Openfactory GmbH | Declared | Observed |
| AS48646 | SDRmedia Verwaltungs GmbH | Declared | Observed |
| AS24482 | SG.GS | not declared | Observed |
| AS401753 | BIXCE Inc | not declared | Observed |
| AS56662 | Marcin Gondek | 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 AS209771 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.
