What to fix

  1. Warning

    16 of 63 announced prefixes have no IRR route object: 189.90.34.0/24, 189.90.41.0/24, 186.193.184.0/22, 189.90.40.0/24, 186.193.184.0/21 (+11).

    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 AS28191 in your RIR’s IRR database (or RADB).
