What to fix

  1. Warning

    10 of 727 announced prefixes have no ROA (RPKI not found): 38.162.120.0/24, 38.162.121.0/24, 38.162.122.0/24, 38.162.123.0/24, 38.162.124.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS18186 and a max length equal to the prefix length:

    38.162.120.0/24 AS18186 max-length /24
38.162.121.0/24 AS18186 max-length /24
38.162.122.0/24 AS18186 max-length /24
38.162.123.0/24 AS18186 max-length /24
38.162.124.0/24 AS18186 max-length /24
38.162.125.0/24 AS18186 max-length /24
38.162.126.0/24 AS18186 max-length /24
38.162.127.0/24 AS18186 max-length /24

38.182.129.0/24 AS18186 max-length /24

  2. Warning

    77 of 727 announced prefixes have no IRR route object: 207.56.248.0/24, 2a10:ce40:231::/48, 149.104.176.0/20, 2602:f7f0:d73::/48, 2602:f7f0:f53::/48 (+72).

    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 AS18186 in your RIR’s IRR database (or RADB).

    route: 207.56.248.0/24
