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 41 are in fix.csv.

| Change | Prefix or set | Detail |
|---|---|---|
| ROA: origin | 2001:558:fc08::/47 | ROAs covering it name AS7922, not AS36732. If AS36732 should announce it, add a ROA for AS36732. |
| Route object: none | 2001:558:fc08::/47 | No route object for it. Add a route object with origin AS36732 in the RIR database for the space. |
| ROA: origin | 2001:55a:900::/40 | ROAs covering it name AS7922, not AS36732. If AS36732 should announce it, add a ROA for AS36732. |
| Route object: none | 2001:55a:900::/40 | No route object for it. Add a route object with origin AS36732 in the RIR database for the space. |
| ROA: none | 192.88.99.0/24 | No ROA covers it. Add a ROA for AS36732, maxLength 24. |

Add a route object with origin AS36732 in the RIR database for the space. |
Route objects not announced
Route objects with origin AS36732 whose prefix no peer sees AS36732 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.
