ROA-based and RPKI-valid-only prefix lists for routers are on asn.ipinfo.app.
RPKI · ASPA
Declared transit providers
No ASPA record This network has not published an ASPA object. ASPA lets a network sign the list of its transit providers, so routers can reject paths that route through anyone else (route leaks). Only a few thousand networks publish one so far, so its absence is normal.
IRR
Registered route objects
Route objects naming AS263541 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 |
|---|---|---|---|---|---|
| 191.241.20.0/22 | RADB | This route object is for a UPX Technologies customer route, which is being exported under this origin AS. This route object was created because no existing route object with the same origin was found, and since some UPX peers filter based on these objects this route may be rejected if this object is not created. Please contact noc@upx.com.br if you have any questions regarding this object. | MAINT-AS52863 | 2023-11-13 | Not announced |
