Announced routes
Every prefix a peer of the route collectors sees with origin AS266471, 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.

AS-SET
PeeringDB's irr_as_set for AS266471: AS-266471. Expanded from the day's IRR dumps the way bgpq4 does against whois.radb.net: a name with a database is read from that database only, one without from the first database in RADB's order. "Not covered" = this network's own routes that a filter built from the set would leave out (AS266471 isn't in the set, or no route object for AS266471 covers the route; more-specifics of a route object are accepted down to /24 and /48, as with bgpq4 -A -R 24 / -R 48). Customers' routes aren't counted: the collectors show each route's origin, not which network it came through.

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 12 are in fix.csv.
- ROA: maxLength1
- Route object: none1
- Route object: RIR9
- Route object: not announced1
| Change | Prefix or set | Detail |
|---|---|---|
| ROA: maxLength | 170.83.50.0/24 | ROA 170.83.48.0/22 AS266471 has maxLength 22; the route is a /24. Raise the maxLength, or add a ROA for 170.83.50.0/24. |
| Route object: none | 170.83.50.0/24 | No route object for it. A route object for 170.83.48.0/22 with origin AS266471 covers it (filters allowing more-specifics accept it). Add a route object with origin AS266471 in the RIR database for the space. |

Route objects not announced
Route objects with origin AS266471 whose prefix no peer sees AS266471 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.
