What to fix

  1. Warning

    10 of 42 announced prefixes have no ROA (RPKI not found): 189.85.64.0/22, 189.85.64.0/23, 189.85.64.0/24, 189.85.65.0/24, 189.85.66.0/23 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS28177 and a max length equal to the prefix length:

    189.85.64.0/22 AS28177 max-length /22
189.85.64.0/23 AS28177 max-length /23
189.85.64.0/24 AS28177 max-length /24
189.85.65.0/24 AS28177 max-length /24
189.85.66.0/23 AS28177 max-length /23
189.85.66.0/24 AS28177 max-length /24
189.85.67.0/24 AS28177 max-length /24
189.85.68.0/22 AS28177 max-length /22
189.85.68.0/23 AS28177 max-length /23
189.85.68.0/24 AS28177 max-length /24

  2. Warning

    41 of 42 announced prefixes have no IRR route object: 2804:2214:800b::/48, 189.85.72.0/22, 189.85.64.0/23, 2804:2214:8000::/33, 2804:2214:c004::/48 (+36).

    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 AS28177 in your RIR’s IRR database (or RADB).

    route6: 2804:2214:800b::/48
origin: AS28177

route: 189.85.72.0/22
origin: AS28177

route: 189.85.64.0/23
