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 10 are in fix.csv.
- ROA: none5
- Route object: none1
- Route object: RIR4
| Change | Prefix or set | Detail |
|---|---|---|
| ROA: none | 177.129.41.0/24 | No ROA covers it. Add a ROA for AS28257, maxLength 24. |
| Route object: none | 177.129.41.0/24 | No route object for it. A route object for 177.129.40.0/21 with origin AS28257 covers it (filters allowing more-specifics accept it). Add a route object with origin AS28257 in the RIR database for the space. |
| ROA: none | 138.36.140.0/22 | No ROA covers it. Add a ROA for AS28257, maxLength 22. |

Route objects not announced
Every route object with origin AS28257 is 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.
