What to fix

  1. Warning

    1 of 9 announced prefixes have no ROA (RPKI not found): 194.56.210.0/24.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS43284 and a max length equal to the prefix length:

    194.56.210.0/24 AS43284 max-length /24

    Open in RPKI / ROA validator Guide

  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.
