Announced routes
Every prefix a peer of the route collectors sees with origin AS27757, things to look at first. Visibility = full-table peers that see it, of 673 (IPv4) and 636 (IPv6) on 75 collectors. Also as routes.csv.

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 139 are in fix.csv.

| Change | Prefix or set | Detail |
|---|---|---|
| Route object: none | 186.42.0.0/24 | Route objects for it name AS28006. A route object for 186.42.0.0/17 with origin AS27757 covers it (filters allowing more-specifics accept it). Add a route object with origin AS27757 in the RIR database for the space. |
| Route object: none | 186.42.128.0/22 | Route objects for it name AS28006. A route object for 186.42.128.0/17 with origin AS27757 covers it (filters allowing more-specifics accept it). Add a route object with origin AS27757 in the RIR database for the space. |
Route objects not announced
Route objects with origin AS27757 whose prefix no peer sees AS27757 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.
