What to fix

Warning

No IPv6 prefixes announced.

Networks without IPv6 force their users through NAT64 or leave them unreachable from IPv6-only networks.

Fix: Get an IPv6 allocation from your RIR (usually free with your IPv4 membership) and announce it.

Open in ASN & BGP prefix lookup
Warning
5 of 5 announced prefixes have no ROA (RPKI not found): 141.193.220.0/23, 141.193.221.0/24, 162.213.68.0/23, 162.213.68.0/24, 162.213.69.0/24.

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

Fix: Create a ROA for each at your RIR portal, with origin AS54037 and a max length equal to the prefix length:
```
141.193.220.0/23 AS54037 max-length /23
141.193.221.0/24 AS54037 max-length /24
162.213.68.0/23 AS54037 max-length /23
162.213.68.0/24 AS54037 max-length /24
162.213.69.0/24 AS54037 max-length /24
```

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.
