|---|---|---|
| Route object: none | 185.104.56.0/24 | No route object for it. A route object for 185.104.56.0/22 with origin AS28821 covers it (filters allowing more-specifics accept it). Add a route object with origin AS28821 in the RIR database for the space. |

Route objects not announced
Route objects with origin AS28821 whose prefix no peer sees AS28821 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.
