What to fix

  1. Warning

    2 of 17 announced prefixes have no IRR route object: 2804:390c::/33, 2804:390c:8000::/33.

    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 AS266520 in your RIR’s IRR database (or RADB).

    route6: 2804:390c::/33
origin: AS266520

  2. Warning

    No public NOC, policy or technical contact.

    Other networks use these addresses to set up peering and to reach you during an incident.

    Fix: Add a role contact (for example noc@ or peering@ an address you monitor) with visibility Public.
