What this network originates
Every prefix observed with AS41051 as its origin, checked against RPKI and the IRR. Problems sort first.
| Prefix | RPKI | IRR | Vantage points |
|---|---|---|---|
| 2a01:20e::/32 | RPKI valid | IRR | 35 |
RPKI · ROAs
Route origin authorisations
Signed statements by address holders that AS41051 may originate these prefixes, up to the maximum length shown.
| Prefix | Max length | Trust anchor |
|---|---|---|
| 2a01:20e::/32 | /32 | RIPENCC |
| 2a13:9500:13e::/48 | /48 | RIPENCC |
ROA-based and RPKI-valid-only prefix lists for routers are on asn.ipinfo.app.
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 |
|---|---|---|---|
| AS6939 | Hurricane Electric LLC | Declared | Observed |
| AS9002 | RETN Limited | Declared | not observed |
| AS39351 | 31173 Services AB | Declared | Observed |
| AS49585 | CoreRoute UG | Declared | not observed |
| AS50629 | LWLcom GmbH | Declared | not observed |
| AS56381 | level66.network UG (haftungsbeschraenkt) | Declared | not observed |
| AS58299 | Openfactory GmbH | 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 AS41051 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.
