What to fix

Warning
6 of 70 announced prefixes have no ROA (RPKI not found): 64.92.96.0/19, 65.101.207.0/24, 192.124.0.0/24, 192.188.61.0/24, 199.165.233.0/24 (+1).

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

Fix: Create a ROA for each at your RIR portal, with origin AS21777 and a max length equal to the prefix length:
```
64.92.96.0/19 AS21777 max-length /19
65.101.207.0/24 AS21777 max-length /24
192.124.0.0/24 AS21777 max-length /24
192.188.61.0/24 AS21777 max-length /24
199.165.233.0/24 AS21777 max-length /24
204.80.248.0/24 AS21777 max-length /24
```

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.
