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 |
|---|---|---|---|
| AS9002 | RETN Limited | Declared | Observed |
| AS41327 | Fiber Telecom S.p.A. | Declared | Observed |
| AS62275 | S.R.L. | Declared | not observed |
| AS6939 | Hurricane Electric LLC | not declared | Observed |
| AS24482 | SG.GS | not declared | Observed |
| AS59919 | Brainbox S.r.l. | not declared | Observed |
| AS8218 | Zayo Infrastructure France SA | 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 AS204471 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.
