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 |
|---|---|---|---|
| AS3257 | GTT Communications Inc. | Declared | Observed |
| AS9141 | P4 Sp. z o.o. | Declared | Observed |
| AS50607 | Stowarzyszenie e-Poludnie | Declared | Observed |
| AS201054 | Stowarzyszenie e-Poludnie | Declared | Observed |
| AS202520 | SkyPass Solutions Sp. z o.o. | Declared | not 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 AS33923 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.
