What to fix

  1. Warning

    10 of 813 announced prefixes have no ROA (RPKI not found): 1.224.0.0/11, 1.224.0.0/13, 1.225.34.0/24, 1.225.88.0/23, 1.226.216.0/23 (+5).

    Without a ROA, networks cannot tell your routes from a hijack.

    Fix: Create a ROA for each at your RIR portal, with origin AS9318 and a max length equal to the prefix length:

    1.224.0.0/11 AS9318 max-length /11
1.224.0.0/13 AS9318 max-length /13
1.225.34.0/24 AS9318 max-length /24
1.225.88.0/23 AS9318 max-length /23
1.226.216.0/23 AS9318 max-length /23
1.227.58.0/23 AS9318 max-length /23
1.230.165.0/24 AS9318 max-length /24
1.230.210.0/23 AS9318 max-length /23
1.230.244.0/23 AS9318 max-length /23
1.231.148.0/23 AS9318 max-length /23

  2. Warning

    9 of 813 announced prefixes have no IRR route object: 39.125.5.0/24, 1.255.42.0/24, 39.116.68.0/24, 39.112.118.0/24, 124.139.232.0/23 (+4).

    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 AS9318 in your RIR’s IRR database (or RADB).

    route: 39.125.5.0/24
origin: AS9318

route: 1.255.42.0/24
origin: AS9318

route: 39.116.68.0/24
origin: AS9318

  3. 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.
