What to fix

Warning

10 of 282 announced prefixes have no ROA (RPKI not found): 23.150.176.0/24, 63.174.226.0/24, 67.219.112.0/22, 67.219.112.0/24, 67.219.113.0/24 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS26077 and a max length equal to the prefix length:

23.150.176.0/24 AS26077 max-length /24
63.174.226.0/24 AS26077 max-length /24
67.219.112.0/22 AS26077 max-length /22
67.219.112.0/24 AS26077 max-length /24
67.219.113.0/24 AS26077 max-length /24
67.219.114.0/24 AS26077 max-length /24

Warning
157 of 282 announced prefixes have no IRR route object: 142.147.117.0/24, 52.144.106.0/24, 107.178.0.0/24, 52.144.103.0/24, 67.219.112.0/24 (+152).

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 AS26077 in your RIR’s IRR database (or RADB).
```
route: 142.147.117.0/24
origin: AS26077

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.
