What to fix

  1. Warning

    11 of 49 announced prefixes have no IRR route object: 95.140.88.0/24, 2001:b28:9a9c::/48, 95.140.90.0/24, 95.161.248.0/24, 2a03:5f80:245::/48 (+6).

    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 AS31500 in your RIR’s IRR database (or RADB).
