What to fix

  1. Warning

    5 of 23 announced prefixes have no ROA (RPKI not found): 45.156.4.0/22, 193.200.110.0/24, 193.200.111.0/24, 194.0.255.0/24, 2001:67c:25a8::/48.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS8218 and a max length equal to the prefix length:

    45.156.4.0/22 AS8218 max-length /22
193.200.110.0/24 AS8218 max-length /24
193.200.111.0/24 AS8218 max-length /24
194.0.255.0/24 AS8218 max-length /24
2001:67c:25a8::/48 AS8218 max-length /48

  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.
