What to fix

Warning
6 of 9 announced prefixes have no ROA (RPKI not found): 185.242.116.0/22, 185.242.116.0/24, 185.242.117.0/24, 185.242.118.0/24, 185.242.119.0/24 (+1).

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

Fix: Create a ROA for each at your RIR portal, with origin AS42971 and a max length equal to the prefix length:
```
185.242.116.0/22 AS42971 max-length /22
185.242.116.0/24 AS42971 max-length /24
185.242.117.0/24 AS42971 max-length /24
185.242.118.0/24 AS42971 max-length /24
185.242.119.0/24 AS42971 max-length /24
2a09:8300::/32 AS42971 max-length /32
```

Warning
1 of 9 announced prefixes have no IRR route object: 31.44.248.0/24.

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 AS42971 in your RIR’s IRR database (or RADB).
```
route: 31.44.248.0/24
origin: AS42971
