What to fix

Warning

10 of 560 announced prefixes have no ROA (RPKI not found): 57.144.0.0/14, 57.145.16.0/23, 66.220.144.0/20, 66.220.144.0/21, 66.220.152.0/21 (+5).

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

Fix: Create a ROA for each at your RIR portal, with origin AS32934 and a max length equal to the prefix length:

57.144.0.0/14 AS32934 max-length /14
57.145.16.0/23 AS32934 max-length /23
66.220.144.0/20 AS32934 max-length /20
66.220.144.0/21 AS32934 max-length /21
66.220.152.0/21 AS32934 max-length /21
69.63.176.0/20 AS32934 max-length /20
69.63.176.0/21 AS32934 max-length /21
69.63.184.0/21 AS32934 max-length /21

Warning
2 of 560 announced prefixes have no IRR route object: 57.145.16.0/23, 2a03:2880:f388::/48.

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 AS32934 in your RIR’s IRR database (or RADB).
```
route: 57.145.16.0/23
origin: AS32934

route6: 2a03:2880:f388::/48
