What to fix

Warning

10 of 133 announced prefixes have no ROA (RPKI not found): 45.132.35.0/24, 64.235.148.0/24, 64.235.149.0/24, 89.46.122.0/24, 89.46.124.0/24 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS8447 and a max length equal to the prefix length:

45.132.35.0/24 AS8447 max-length /24
64.235.148.0/24 AS8447 max-length /24
64.235.149.0/24 AS8447 max-length /24
89.46.122.0/24 AS8447 max-length /24
89.46.124.0/24 AS8447 max-length /24
91.201.171.0/24 AS8447 max-length /24
91.206.192.0/23 AS8447 max-length /23
91.209.219.0/24 AS8447 max-length /24

Warning
5 of 133 announced prefixes have no IRR route object: 157.247.1.0/24, 157.247.128.0/24, 64.235.148.0/24, 64.235.149.0/24, 157.247.0.0/24.

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 AS8447 in your RIR’s IRR database (or RADB).
```
route: 157.247.1.0/24
origin: AS8447

route: 157.247.128.0/24
origin: AS8447

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.
