What to fix

  1. Warning

    10 of 118 announced prefixes have no ROA (RPKI not found): 49.254.80.0/24, 49.254.105.0/24, 59.150.0.0/21, 59.150.12.0/24, 59.150.14.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS9457 and a max length equal to the prefix length:

    49.254.80.0/24 AS9457 max-length /24
49.254.105.0/24 AS9457 max-length /24
59.150.0.0/21 AS9457 max-length /21
59.150.12.0/24 AS9457 max-length /24
59.150.14.0/24 AS9457 max-length /24
59.150.16.0/23 AS9457 max-length /23
59.150.22.0/23 AS9457 max-length /23
59.150.42.0/24 AS9457 max-length /24
59.150.45.0/24 AS9457 max-length /24
59.150.46.0/23 AS9457 max-length /23

  2. Warning

    53 of 118 announced prefixes have no IRR route object: 185.199.212.0/23, 59.150.144.0/23, 211.175.242.0/23, 59.150.172.0/24, 59.150.46.0/23 (+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 AS9457 in your RIR’s IRR database (or RADB).
