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
4 of 4 announced prefixes have no ROA (RPKI not found): 170.81.204.0/24, 170.81.205.0/24, 170.81.206.0/24, 170.81.207.0/24.

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

Fix: Create a ROA for each at your RIR portal, with origin AS266422 and a max length equal to the prefix length:
```
170.81.204.0/24 AS266422 max-length /24
170.81.205.0/24 AS266422 max-length /24
170.81.206.0/24 AS266422 max-length /24
170.81.207.0/24 AS266422 max-length /24
```

Warning
4 of 4 announced prefixes have no IRR route object: 170.81.205.0/24, 170.81.207.0/24, 170.81.206.0/24, 170.81.204.0/24.

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 AS266422 in your RIR’s IRR database (or RADB).
```
route: 170.81.205.0/24
origin: AS266422

route: 170.81.207.0/24
origin: AS266422

route: 170.81.206.0/24
origin: AS266422
