What to fix

  1. Warning

    7 of 21 announced prefixes have no IRR route object: 77.51.192.0/21, 77.51.224.0/21, 77.51.176.0/21, 77.51.208.0/21, 77.51.184.0/21 (+2).

    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 AS25515 in your RIR’s IRR database (or RADB).
