Fix list
The changes that would bring RPKI, the IRR and what's announced into line. Some are deliberate (a route object kept for a backup route, say); the network decides. All 5 are in fix.csv.
- ROA: origin1
- Route object: none1
- Route object: RIR2
- Route object: not announced1
| Change | Prefix or set | Detail |
|---|---|---|
| ROA: origin | 143.20.121.0/24 | ROAs covering it name AS834, not AS56913. If AS56913 should announce it, add a ROA for AS56913. |
| Route object: none | 143.20.121.0/24 | No route object for it. Add a route object with origin AS56913 in the RIR database for the space. |
| Route object: RIR | 102.135.19.0/24 | Route object only in RADB. Add it in the RIR database for the space. |
| Route object: RIR | 102.135.99.0/24 | Route object only in RADB. Add it in the RIR database for the space. |
Route objects not announced
Route objects with origin AS56913 whose prefix no peer sees AS56913 announce. Many are kept on purpose (backup routes, space announced only in some places).

Routes: the 08:00 UTC snapshots of 2026-11-12 from 75 RIPE RIS and RouteViews collectors. RPKI: our rpki-client run before the snapshot. IRR: the day's dumps of the five RIR databases and RADB's mirrors. The LEVEL3 and IDNIC databases publish no dump and aren't read, so route objects only there count as none.
