Announced routes

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 29 are in fix.csv.

| Change | Prefix or set | Detail |
|---|---|---|
| ROA: origin | 106.3.84.0/22 | An AS0 ROA covers it (the holder's statement that it shouldn't be routed). If AS2042 should announce it, add a ROA for AS2042. |
| Route object: none | 106.3.84.0/22 | Route objects for it name AS4058, AS9269, AS17554. Add a route object with origin AS2042 in the RIR database for the space. |
| ROA: origin | 106.3.84.0/24 | An AS0 ROA covers it (the holder's statement that it shouldn't be routed). If AS2042 should announce it, add a ROA for AS2042. |
| Route object: none | 106.3.84.0/24 | No route object for it. Add a route object with origin AS2042 in the RIR database for the space. |
| ROA: origin | 106.3.87.0/24 | An AS0 ROA covers it (the holder's statement that it shouldn't be routed). If AS2042 should announce it, add a ROA for AS2042. |

Route objects not announced
Route objects with origin AS2042 whose prefix no peer sees AS2042 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.
