| Route object: none | 138.47.224.0/19 | No route object for it. A route object for 138.47.0.0/16 with origin AS19564 covers it (filters allowing more-specifics accept it). Add a route object with origin AS19564 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.
