Warning

10 of 82 announced prefixes have no ROA (RPKI not found): 177.131.197.0/24, 177.131.224.0/24, 177.131.237.0/24, 177.131.239.0/24, 187.110.64.0/19 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS28624 and a max length equal to the prefix length:

177.131.197.0/24 AS28624 max-length /24
177.131.224.0/24 AS28624 max-length /24
177.131.237.0/24 AS28624 max-length /24
177.131.239.0/24 AS28624 max-length /24
187.110.64.0/19 AS28624 max-length /19

Warning
10 of 82 announced prefixes have no IRR route object: 187.110.108.0/24, 177.131.224.0/24, 177.131.237.0/24, 177.131.239.0/24, 177.131.197.0/24 (+5).

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 AS28624 in your RIR’s IRR database (or RADB).
```
route: 187.110.108.0/24
origin: AS28624

route: 177.131.224.0/24
origin: AS28624

route: 177.131.237.0/24
origin: AS28624
```

Warning

No IRR as-set is listed.

Peers and route servers build prefix filters from the as-set. Without one they fall back to the AS number alone, which breaks as soon as you have customers.

Fix: Create an as-set in your RIR’s IRR database and add it to your PeeringDB record.
