What to fix

Warning

10 of 339 announced prefixes have no ROA (RPKI not found): 38.67.216.0/24, 38.69.225.0/24, 38.86.91.0/24, 38.86.228.0/24, 38.86.229.0/24 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS46475 and a max length equal to the prefix length:

38.67.216.0/24 AS46475 max-length /24
38.69.225.0/24 AS46475 max-length /24
38.86.91.0/24 AS46475 max-length /24
38.86.228.0/24 AS46475 max-length /24
38.86.229.0/24 AS46475 max-length /24
38.92.61.0/24 AS46475 max-length /24
38.95.35.0/24 AS46475 max-length /24
38.96.30.0/24 AS46475 max-length /24
38.96.31.0/24 AS46475 max-length /24
38.96.68.0/24 AS46475 max-length /24

Warning
145 of 339 announced prefixes have no IRR route object: 64.31.13.0/24, 208.115.255.0/24, 64.31.29.0/24, 74.63.202.0/24, 64.31.47.0/24 (+140).

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 AS46475 in your RIR’s IRR database (or RADB).
```
route: 64.31.13.0/24
origin: AS46475

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.
