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 3 are in fix.csv.
- ROA: none1
- Route object: none1
- Route object: not announced1
| Change | Prefix or set | Detail |
|---|---|---|

| Route object: none | 8.39.192.0/21 | No route object for it. Add a route object with origin AS54396 in the RIR database for the space. |
Route objects not announced
Route objects with origin AS54396 whose prefix no peer sees AS54396 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.
