What to fix

Warning

10 of 112 announced prefixes have no ROA (RPKI not found): 38.46.72.0/21, 38.46.72.0/24, 38.46.73.0/24, 38.46.74.0/24, 38.46.75.0/24 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS398704 and a max length equal to the prefix length:

38.46.72.0/21 AS398704 max-length /21
38.46.72.0/24 AS398704 max-length /24
38.46.73.0/24 AS398704 max-length /24
38.46.74.0/24 AS398704 max-length /24
38.46.75.0/24 AS398704 max-length /24
38.46.76.0/24 AS398704 max-length /24
38.46.77.0/24 AS398704 max-length /24

Warning
13 of 112 announced prefixes have no IRR route object: 2406:dd80:800::/38, 38.181.80.0/24, 2405:5240::/38, 2405:5240:800::/38, 113.203.255.0/24 (+8).

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 AS398704 in your RIR’s IRR database (or RADB).
```
route6: 2406:dd80:800::/38
origin: AS398704

route: 38.181.80.0/24
origin: AS398704

route6: 2405:5240::/38
origin: AS398704
