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 42 are in fix.csv.

| ROA: none | 148.142.80.0/21 | No ROA covers it. Add a ROA for AS20004, maxLength 21. |
| Route object: none | 148.142.80.0/21 | No route object for it. A route object for 148.142.64.0/19 with origin AS20004 covers it (filters allowing more-specifics accept it). Add a route object with origin AS20004 in the RIR database for the space. |

Route objects not announced
Route objects with origin AS20004 whose prefix no peer sees AS20004 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.
