What to fix

Warning

10 of 295 announced prefixes have no ROA (RPKI not found): 8.243.170.0/24, 38.50.50.0/24, 168.227.244.0/22, 168.227.244.0/24, 168.227.245.0/24 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS262191 and a max length equal to the prefix length:

8.243.170.0/24 AS262191 max-length /24
38.50.50.0/24 AS262191 max-length /24
168.227.244.0/22 AS262191 max-length /22
168.227.244.0/24 AS262191 max-length /24
168.227.245.0/24 AS262191 max-length /24

Warning
148 of 295 announced prefixes have no IRR route object: 190.131.255.0/24, 190.131.203.0/24, 2800:b70:2001::/48, 168.227.246.0/24, 190.131.213.0/24 (+143).

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 AS262191 in your RIR’s IRR database (or RADB).
```
route: 190.131.255.0/24
origin: AS262191

route: 190.131.203.0/24
origin: AS262191

route6: 2800:b70:2001::/48
origin: AS262191
```

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.
