What to fix

Warning
8 of 11 announced prefixes have no ROA (RPKI not found): 83.223.96.0/19, 89.145.64.0/18, 89.145.76.0/22, 185.32.105.0/24, 185.32.106.0/23 (+3).

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

Fix: Create a ROA for each at your RIR portal, with origin AS29017 and a max length equal to the prefix length:
```
83.223.96.0/19 AS29017 max-length /19
89.145.64.0/18 AS29017 max-length /18
89.145.76.0/22 AS29017 max-length /22
185.32.105.0/24 AS29017 max-length /24
185.32.106.0/23 AS29017 max-length /23
193.227.111.0/24 AS29017 max-length /24
212.113.128.0/19 AS29017 max-length /19
2a00:14f0::/32 AS29017 max-length /32

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.
