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 179 are in fix.csv.

| ROA: maxLength | 103.16.252.32/27 | ROA 103.16.252.0/23 AS6421 has maxLength 23; the route is a /27. Raise the maxLength, or add a ROA for 103.16.252.32/27. |
| Route object: none | 103.16.252.32/27 | No route object for it. A route object for 103.16.252.0/23 with origin AS6421 covers it (too long for filters allowing more-specifics up to /24). Add a route object with origin AS6421 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.
