What to fix

  1. Warning

    1 of 36 announced prefixes have no IRR route object: 140.96.0.0/19.

    Many networks build their prefix filters from IRR data; without route objects some of them drop the routes.

    Fix: Create route (IPv4) and route6 (IPv6) objects with origin AS18422 in your RIR’s IRR database (or RADB).

    route: 140.96.0.0/19
origin: AS18422

  2. Warning

    No IRR as-set is listed.

    Peers and route servers build prefix filters from the as-set. Without one they fall back to the AS number alone, which breaks as soon as you have customers.

    Fix: Create an as-set in your RIR’s IRR database and add it to your PeeringDB record.
