What to fix

Warning
6 of 21 announced prefixes have no ROA (RPKI not found): 91.208.167.0/24, 185.171.32.0/22, 185.171.33.0/24, 193.176.205.0/24, 193.242.183.0/24 (+1).

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

Fix: Create a ROA for each at your RIR portal, with origin AS39700 and a max length equal to the prefix length:
```
91.208.167.0/24 AS39700 max-length /24
185.171.32.0/22 AS39700 max-length /22
185.171.33.0/24 AS39700 max-length /24
193.176.205.0/24 AS39700 max-length /24
193.242.183.0/24 AS39700 max-length /24
194.242.54.0/24 AS39700 max-length /24

Warning
8 of 21 announced prefixes have no IRR route object: 185.228.196.0/22, 185.171.33.0/24, 2001:4cb8:59c::/48, 85.10.171.0/24, 2001:4cb9::/32 (+3).

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 AS39700 in your RIR’s IRR database (or RADB).
```
route: 185.228.196.0/22
origin: AS39700

route: 185.171.33.0/24
origin: AS39700

route6: 2001:4cb8:59c::/48
origin: AS39700
```

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.
