What to fix

Warning

10 of 16 announced prefixes have no ROA (RPKI not found): 200.24.120.0/23, 200.24.120.0/24, 200.24.121.0/24, 200.24.122.0/24, 200.24.123.0/24 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS271600 and a max length equal to the prefix length:

200.24.120.0/23 AS271600 max-length /23
200.24.120.0/24 AS271600 max-length /24
200.24.121.0/24 AS271600 max-length /24
200.24.122.0/24 AS271600 max-length /24
200.24.123.0/24 AS271600 max-length /24
2804:7e10:4000::/34 AS271600 max-length /34

Warning
4 of 16 announced prefixes have no IRR route object: 2804:7e10:8000::/36, 2804:7e10:b000::/36, 2804:7e10:a000::/36, 2804:7e10:9000::/36.

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 AS271600 in your RIR’s IRR database (or RADB).
```
route6: 2804:7e10:8000::/36
origin: AS271600

route6: 2804:7e10:b000::/36
origin: AS271600

route6: 2804:7e10:a000::/36
origin: AS271600
```

Warning

No IRR as-set is listed.

Peers and route servers build prefix filters from the as-set. Without one they fall back to the AS number alone, which breaks as soon as you have customers.

Fix: Create an as-set in your RIR’s IRR database and add it to your PeeringDB record.
