What to fix

Warning
1 of 24 announced prefixes have no ROA (RPKI not found): 103.194.72.0/22.

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

Fix: Create a ROA for each at your RIR portal, with origin AS18260 and a max length equal to the prefix length:
```
103.194.72.0/22 AS18260 max-length /22
```
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.
