What to fix

  1. Warning

    10 of 214 announced prefixes have no ROA (RPKI not found): 38.49.128.0/24, 38.49.129.0/24, 38.49.130.0/24, 38.49.131.0/24, 38.49.132.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS28458 and a max length equal to the prefix length:

    38.49.128.0/24 AS28458 max-length /24
38.49.129.0/24 AS28458 max-length /24
38.49.130.0/24 AS28458 max-length /24
38.49.131.0/24 AS28458 max-length /24
38.49.132.0/24 AS28458 max-length /24
38.49.133.0/24 AS28458 max-length /24
38.49.134.0/24 AS28458 max-length /24
38.49.135.0/24 AS28458 max-length /24
38.49.136.0/24 AS28458 max-length /24
38.49.137.0/24 AS28458 max-length /24

  2. Warning

    99 of 214 announced prefixes have no IRR route object: 206.135.88.0/24, 206.135.13.0/24, 206.135.14.0/24, 206.135.73.0/24, 206.135.30.0/24 (+94).

    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 AS28458 in your RIR’s IRR database (or RADB).
