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 |
|---|---|---|---|
| AS28158 | Ampernet Telecomunicacoes Ltda | Declared | Observed |
| AS6939 | Hurricane Electric LLC | not declared | Observed |
| AS24482 | SG.GS | not declared | Observed |
| AS37721 | Virtual Technologies & Solutions | 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 AS262657 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 |
|---|---|---|---|---|---|
| 200.7.0.0/22 | NTTCOM | Proxy Route For ASN262657 | MAINT-AS263949 | 2017-02-08 | Announced |
