What to fix

  1. Warning

    6 of 11 announced prefixes have no IRR route object: 190.4.78.0/24, 190.4.72.0/21, 200.6.150.0/23, 186.159.104.0/21, 190.4.64.0/21 (+1).

    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 AS27745 in your RIR’s IRR database (or RADB).

    route: 190.4.78.0/24
origin: AS27745

route: 190.4.72.0/21
origin: AS27745

route: 200.6.150.0/23
origin: AS27745

  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.
