What to fix

Warning
1 of 3 announced prefixes have no ROA (RPKI not found): 143.246.177.0/24.

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

Fix: Create a ROA for each at your RIR portal, with origin AS61218 and a max length equal to the prefix length:
```
143.246.177.0/24 AS61218 max-length /24
```
Open in RPKI / ROA validator Guide
Warning
1 of 3 announced prefixes have no IRR route object: 2a14:c700::/29.

Many networks build their prefix filters from IRR data; without route objects some of them drop the routes.

Fix: Create route (IPv4) and route6 (IPv6) objects with origin AS61218 in your RIR’s IRR database (or RADB).
```
route6: 2a14:c700::/29
origin: AS61218
```

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.
