What to fix

Warning
2 of 12 announced prefixes have no IRR route object: 2a0f:b240:5efd::/48, 2a0a:6040:b825::/48.

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 AS200731 in your RIR’s IRR database (or RADB).
```
route6: 2a0f:b240:5efd::/48
origin: AS200731

route6: 2a0a:6040:b825::/48
origin: AS200731
```

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.
