What to fix

Warning

10 of 143 announced prefixes have no ROA (RPKI not found): 64.30.240.0/20, 136.223.36.0/24, 137.124.0.0/16, 137.124.10.0/24, 150.154.0.0/16 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS11351 and a max length equal to the prefix length:

64.30.240.0/20 AS11351 max-length /20
136.223.36.0/24 AS11351 max-length /24
137.124.0.0/16 AS11351 max-length /16
137.124.10.0/24 AS11351 max-length /24
150.154.0.0/16 AS11351 max-length /16
167.254.206.0/24 AS11351 max-length /24

Warning
18 of 143 announced prefixes have no IRR route object: 2600:6000:5ea::/48, 98.10.0.0/15, 167.254.207.0/24, 2605:ed00:4c63::/48, 2600:6000:fb34::/48 (+13).

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 AS11351 in your RIR’s IRR database (or RADB).
```
route6: 2600:6000:5ea::/48
origin: AS11351

route: 98.10.0.0/15
origin: AS11351

route: 167.254.207.0/24
origin: AS11351
