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 8 are in fix.csv.
- ROA: none1
- Route object: none1
- Route object: RIR4
- Route object: not announced2
| Change | Prefix or set | Detail |
|---|---|---|
| ROA: none | 157.142.0.0/16 | No ROA covers it. Add a ROA for AS16922, maxLength 16. |
| Route object: RIR | 157.142.0.0/16 | Route object only in RADB. Add it in the RIR database for the space. |
| Route object: none | 156.110.255.0/24 | No route object for it. A route object for 156.110.240.0/20 with origin AS16922 covers it (filters allowing more-specifics accept it). Add a route object with origin AS16922 in the RIR database for the space. |
| Route object: RIR | 156.110.160.0/19 | Route object only in RADB. Add it in the RIR database for the space. |
| Route object: RIR | 156.110.144.0/20 | Route object only in RADB. Add it in the RIR database for the space. |
| Route object: RIR | 156.110.240.0/20 | Route object only in RADB. Add it in the RIR database for the space. |
Route objects not announced
Route objects with origin AS16922 whose prefix no peer sees AS16922 announce. Many are kept on purpose (backup routes, space announced only in some places).
| 199.120.0.0/21 | RADB | No ROA |
| 199.120.8.0/22 | RADB | No ROA |
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.
