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 | not observed |
| AS196610 | DE-CIX Management GmbH | 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 AS41731 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.
| Prefix | Source | Description | Maintainer | Changed | Routing |
|---|---|---|---|---|---|
| 45.91.60.0/22 | RIPE | route object for 45.91.60.0/22 | MOOS-MNT | 2025-12-31 | Announced |
