Announced routes

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 objects not announced

Route objects with origin AS3401 whose prefix no peer sees AS3401 announce. Many are kept on purpose (backup routes, space announced only in some places).

156.74.0.0/16RADBNo ROA

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.
