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 7 are in fix.csv.

Route object: none168.168.16.0/23No route object for it. A route object for 168.168.16.0/22 with origin AS43949 covers it (filters allowing more-specifics accept it). Add a route object with origin AS43949 in the RIR database for the space.671 of 673

Route objects not announced

Route objects with origin AS43949 whose prefix no peer sees AS43949 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.
