| Change | Prefix or set | Detail |
|---|---|---|
| ROA: none | 2001:df7:7800::/49 | No ROA covers it. Add a ROA for AS17523, maxLength 49. |
| Route object: none | 2001:df7:7800::/49 | No route object for it. A route object for 2001:df7:7800::/48 with origin AS17523 covers it (too long for filters allowing more-specifics up to /48). Add a route object with origin AS17523 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.
