What to fix

Warning
2 of 2 announced prefixes have no ROA (RPKI not found): 185.153.20.0/22, 2a0d:ab80::/32.

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

Fix: Create a ROA for each at your RIR portal, with origin AS204523 and a max length equal to the prefix length:
```
185.153.20.0/22 AS204523 max-length /22
2a0d:ab80::/32 AS204523 max-length /32
```
Open in RPKI / ROA validator Guide
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.
