| Change | Prefix or set | Detail |
|---|---|---|
| ROA: none | 198.105.1.0/24 | No ROA covers it. Add a ROA for AS18639, maxLength 24. |
| Route object: none | 198.105.1.0/24 | No route object for it. A route object for 198.105.0.0/22 with origin AS18639 covers it (filters allowing more-specifics accept it). Add a route object with origin AS18639 in the RIR database for the space. |
Route objects not announced

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.
