What to fix

Warning

10 of 131 announced prefixes have no ROA (RPKI not found): 5.83.224.0/21, 80.254.32.0/20, 91.135.128.0/20, 136.238.227.0/24, 137.47.41.0/24 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS25400 and a max length equal to the prefix length:

5.83.224.0/21 AS25400 max-length /21
80.254.32.0/20 AS25400 max-length /20
91.135.128.0/20 AS25400 max-length /20
136.238.227.0/24 AS25400 max-length /24
137.47.41.0/24 AS25400 max-length /24
137.217.224.0/24 AS25400 max-length /24
138.62.0.0/16 AS25400 max-length /16

Warning
43 of 131 announced prefixes have no IRR route object: 159.171.176.0/20, 178.17.144.0/20, 80.254.32.0/20, 84.214.128.0/17, 159.171.192.0/19 (+38).

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 AS25400 in your RIR’s IRR database (or RADB).
```
route: 159.171.176.0/20
origin: AS25400

route: 178.17.144.0/20
origin: AS25400

route: 80.254.32.0/20
origin: AS25400
```

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.
