What to fix

  1. Warning

    1 of 163 announced prefixes have no IRR route object: 2a12:a303:104::/48.

    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 AS3258 in your RIR’s IRR database (or RADB).

origin: AS3258
