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 |
|---|---|---|---|
| AS2914 | NTT America, Inc. | Declared | Observed |
| AS26615 | TIM S/A | Declared | Observed |
| AS28663 | FLYS INTERATIVA LTDA | Declared | Observed |
| AS52863 | UPX TECNOLOGIA LTDA | Declared | Observed |
| AS262444 | XTURBO PROVEDOR DE INTERNET LTDA | Declared | Observed |
| AS6939 | Hurricane Electric LLC | not declared | Observed |
| AS22381 | SAMM TECNOLOGIA E TELECOMUNICACOES S.A | not declared | Observed |
| AS24482 | SG.GS | 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 AS27720 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.
