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 22 are in fix.csv.

| Change | Prefix or set | Detail |
|---|---|---|
| ROA: none | 77.234.200.0/24 | No ROA covers it. Add a ROA for AS42289, maxLength 24. |
| Route object: none | 77.234.200.0/24 | No route object for it. A route object for 77.234.200.0/23 with origin AS42289 covers it (filters allowing more-specifics accept it). Add a route object with origin AS42289 in the RIR database for the space. |
| ROA: none | 77.234.207.0/28 | No ROA covers it. Add a ROA for AS42289, maxLength 28. |
| Route object: none | 77.234.207.0/28 | No route object for it. A route object for 77.234.192.0/19 with origin AS42289 covers it (too long for filters allowing more-specifics up to /24). Add a route object with origin AS42289 in the RIR database for the space. |

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.
