Declared transit providers
This network has signed an ASPA record naming its transit providers. Each is compared against the upstreams observed in routing paths.

| AS16205 | DSI GmbH Daten Service Informationssysteme | Declared | not observed |
| AS57328 | unnamed | Declared | not observed |
| AS59552 | unnamed | Declared | not observed |

| AS211479 | Ember Keske | Declared | not observed |
| AS216188 | Bieber IT GmbH | Declared | not 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 AS213973 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.
No route objects name this AS as origin.
IRR
AS-sets
The as-set is what upstreams expand to build this network's customer filter. Sets that list AS213973 directly show who expects to carry it.
No as-set lists this AS directly.
