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
9 of 63 announced prefixes have no ROA (RPKI not found): 66.185.176.0/20, 198.80.42.0/23, 198.80.42.0/24, 198.217.136.0/22, 198.217.216.0/22 (+4).

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

Fix: Create a ROA for each at your RIR portal, with origin AS2559 and a max length equal to the prefix length:
```
66.185.176.0/20 AS2559 max-length /20
198.80.42.0/23 AS2559 max-length /23
198.80.42.0/24 AS2559 max-length /24
198.217.136.0/22 AS2559 max-length /22
198.217.216.0/22 AS2559 max-length /22
198.217.224.0/22 AS2559 max-length /22
198.217.240.0/21 AS2559 max-length /21
198.241.128.0/17 AS2559 max-length /17
199.68.156.0/24 AS2559 max-length /24
```

Warning
1 of 63 announced prefixes have no IRR route object: 198.217.227.0/24.

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 AS2559 in your RIR’s IRR database (or RADB).
```
route: 198.217.227.0/24
origin: AS2559
```

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.
