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 19 are in fix.csv.

| Change | Prefix or set | Detail |
|---|---|---|
| ROA: maxLength | 2401:b080:141::/48 | ROA 2401:b080::/32 AS133748 has maxLength 32; the route is a /48. Raise the maxLength, or add a ROA for 2401:b080:141::/48. |
| Route object: none | 2401:b080:141::/48 | No route object for it. A route object for 2401:b080::/32 with origin AS133748 covers it (filters allowing more-specifics accept it). Add a route object with origin AS133748 in the RIR database for the space. |
| ROA: maxLength | 2401:b080:651::/48 | ROA 2401:b080::/32 AS133748 has maxLength 32; the route is a /48. Raise the maxLength, or add a ROA for 2401:b080:651::/48. |

Route objects not announced
Route objects with origin AS133748 whose prefix no peer sees AS133748 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.
