What to fix

  1. Warning

    5 of 8 announced prefixes have no ROA (RPKI not found): 149.5.55.0/24, 149.5.56.0/24, 149.5.57.0/24, 149.5.58.0/24, 154.56.236.0/24.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS210893 and a max length equal to the prefix length:

    149.5.55.0/24 AS210893 max-length /24
149.5.56.0/24 AS210893 max-length /24
149.5.57.0/24 AS210893 max-length /24
149.5.58.0/24 AS210893 max-length /24
154.56.236.0/24 AS210893 max-length /24

  2. Warning

    1 of 8 announced prefixes have no IRR route object: 2a11:2c80::/29.

    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 AS210893 in your RIR’s IRR database (or RADB).

    route6: 2a11:2c80::/29
origin: AS210893

  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.
