| 23.138.113.0/24 | RPKI valid | IRR | 57 |
| 23.138.114.0/23 | RPKI valid | IRR covering | 57 |

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 |
|---|---|---|---|
| AS12129 | 123.Net, Inc. | Declared | Observed |
| AS14103 | ACD.net | Declared | Observed |
| AS20205 | Amplex Electric, Inc. | 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 AS267 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.
