RPKI · ROAs
Route origin authorisations
Signed statements by address holders that AS47757 may originate these prefixes, up to the maximum length shown.
| Prefix | Max length | Trust anchor |
|---|---|---|
| 31.40.206.0/24 | /24 | RIPENCC |
| 2a0c:b641:f0::/44 | /128 | 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 |
|---|---|---|---|
| AS34984 | Superonline Iletisim Hizmetleri A.S. | Declared | not observed |
| AS201160 | Dogus Bilgi Islem ve Teknoloji Hizmetleri A.S | 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 AS47757 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.
