What this network originates
Every prefix observed with AS13020 as its origin, checked against RPKI and the IRR. Problems sort first.
| Prefix | RPKI | IRR | Vantage points |
|---|---|---|---|
| 94.45.224.0/19 | RPKI valid | IRR | 55 |
| 2001:67c:20a1::/48 | RPKI valid | IRR | 31 |
RPKI · ROAs
Route origin authorisations
Signed statements by address holders that AS13020 may originate these prefixes, up to the maximum length shown.
| Prefix | Max length | Trust anchor |
|---|---|---|
| 94.45.224.0/19 | /19 | RIPENCC |
| 2001:67c:20a1::/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 |
|---|---|---|---|
| AS553 | Universitaet Stuttgart | Declared | not observed |
| AS50472 | Chaos Computer Club e.V. | 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 AS13020 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.
| Prefix | Source | Description | Maintainer | Changed | Routing |
|---|---|---|---|---|---|
| 94.45.224.0/19 | RIPE | 94.45.224.0/19 via AS13020 at the Event | CHAOS-MNT | 2016-08-15 | Announced |
| 2001:67c:20a1::/48 | RIPE | Event Network via AS13020 | CHAOS-MNT | 2011-07-07 | Announced |

AS-sets
The as-set is what upstreams expand to build this network's customer filter. Sets that list AS13020 directly show who expects to carry it.
