What to fix

Warning

10 of 261 announced prefixes have no ROA (RPKI not found): 43.227.16.0/24, 43.239.108.0/24, 43.240.64.0/24, 43.240.65.0/24, 43.240.66.0/24 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS133296 and a max length equal to the prefix length:

43.227.16.0/24 AS133296 max-length /24
43.239.108.0/24 AS133296 max-length /24
43.240.64.0/24 AS133296 max-length /24
43.240.65.0/24 AS133296 max-length /24
43.240.66.0/24 AS133296 max-length /24
43.240.67.0/24 AS133296 max-length /24

Warning
83 of 261 announced prefixes have no IRR route object: 185.230.100.0/24, 31.58.112.0/24, 31.59.49.0/24, 103.123.74.0/24, 103.119.239.0/24 (+78).

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 AS133296 in your RIR’s IRR database (or RADB).
```
route: 185.230.100.0/24
origin: AS133296

route: 31.58.112.0/24
origin: AS133296
