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 16 are in fix.csv.

| Change | Prefix or set | Detail |
|---|---|---|
| Route object: none | 208.70.64.0/24 | No route object for it. A route object for 208.70.64.0/23 with origin AS21858 covers it (filters allowing more-specifics accept it). Add a route object with origin AS21858 in the RIR database for the space. |
| Route object: RIR | 2607:ffa8::/32 | Route object only in RADB. Add it in the RIR database for the space. |
Route objects not announced
Route objects with origin AS21858 whose prefix no peer sees AS21858 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.
