AS-SET
PeeringDB's irr_as_set for AS131918: AS131918. 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 (AS131918 isn't in the set, or no route object for AS131918 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 26 are in fix.csv.

Route objects not announced
Every route object with origin AS131918 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.
