What to fix

Problem

2 of 85 announced prefixes are RPKI invalid: 154.211.168.0/21, 154.211.176.0/21.

A ROA covers them but does not allow this origin or prefix length, so networks that filter (most large ones do) drop these routes.

Fix: Fix the ROAs (origin AS and max length) at your RIR, or stop announcing the routes.

Open in RPKI / ROA validator Guide
Warning
8 of 85 announced prefixes have no ROA (RPKI not found): 45.196.80.0/21, 121.78.23.0/24, 156.255.16.0/20, 2402:620:2e::/48, 2402:620:2f::/48 (+3).

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

Fix: Create a ROA for each at your RIR portal, with origin AS17497 and a max length equal to the prefix length:
```
45.196.80.0/21 AS17497 max-length /21
121.78.23.0/24 AS17497 max-length /24
156.255.16.0/20 AS17497 max-length /20
2402:620:2e::/48 AS17497 max-length /48
2402:620:2f::/48 AS17497 max-length /48
2402:620:20::/48 AS17497 max-length /48
2402:620:21::/48 AS17497 max-length /48
2402:620:26::/48 AS17497 max-length /48
```

Warning
1 of 85 announced prefixes have no IRR route object: 45.196.80.0/21.

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 AS17497 in your RIR’s IRR database (or RADB).
