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 |
| AS29075 | IELO-LIAZO SERVICES SAS | Declared | Observed |
| AS39305 | Groupe convergence.com SAS | Declared | Observed |
| AS59689 | Code40 SAS | Declared | not observed |
| AS24482 | SG.GS | not declared | Observed |
| AS50628 | Leonix Telecom SAS | not declared | Observed |
| AS12779 | IT.Gate S.p.A. | not declared | Observed |
| AS37721 | Virtual Technologies & Solutions | not declared | Observed |
| AS39801 | France IX Services SASU | 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 AS58308 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.
