What to fix

  1. Warning

    10 of 43 announced prefixes have no ROA (RPKI not found): 38.2.160.0/19, 38.87.232.0/21, 38.107.88.0/21, 67.206.200.0/21, 69.24.197.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS21559 and a max length equal to the prefix length:

    38.2.160.0/19 AS21559 max-length /19
38.87.232.0/21 AS21559 max-length /21
38.107.88.0/21 AS21559 max-length /21
67.206.200.0/21 AS21559 max-length /21
69.24.197.0/24 AS21559 max-length /24
69.24.198.0/24 AS21559 max-length /24
69.24.199.0/24 AS21559 max-length /24
69.24.200.0/24 AS21559 max-length /24
72.46.156.0/23 AS21559 max-length /23
149.18.21.0/24 AS21559 max-length /24

  2. Warning

    4 of 43 announced prefixes have no IRR route object: 74.119.24.0/24, 192.254.109.0/24, 200.5.22.0/24, 200.5.23.0/24.

    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 AS21559 in your RIR’s IRR database (or RADB).

    route: 74.119.24.0/24
origin: AS21559

route: 192.254.109.0/24
origin: AS21559

route: 200.5.22.0/24
origin: AS21559

  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.
