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 |
|---|---|---|---|
| AS174 | Cogent Communications, LLC | Declared | Observed |
| AS1299 | Arelion Sweden AB | Declared | not observed |
| AS3257 | GTT Communications Inc. | Declared | not observed |
| AS3356 | Level 3 Parent, LLC | Declared | Observed |
| AS27552 | TowardEX Technologies International, Inc. | Declared | Observed |
| AS395748 | NetSpeed LLC | Declared | Observed |
| AS6939 | Hurricane Electric LLC | not declared | Observed |
| AS293 | ESnet | 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 AS397700 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.
