What to fix

  1. Warning

    10 of 11 announced prefixes have no ROA (RPKI not found): 85.31.172.0/22, 85.208.128.0/22, 164.40.192.0/20, 185.76.164.0/22, 185.76.164.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS198225 and a max length equal to the prefix length:

    85.31.172.0/22 AS198225 max-length /22
85.208.128.0/22 AS198225 max-length /22
164.40.192.0/20 AS198225 max-length /20
185.76.164.0/22 AS198225 max-length /22
185.76.164.0/24 AS198225 max-length /24
185.76.167.0/24 AS198225 max-length /24

  2. Warning

    1 of 11 announced prefixes have no IRR route object: 185.76.164.0/24.

    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 AS198225 in your RIR’s IRR database (or RADB).

origin: AS198225

  3. Warning

    No public NOC, policy or technical contact.

    Other networks use these addresses to set up peering and to reach you during an incident.

    Fix: Add a role contact (for example noc@ or peering@ an address you monitor) with visibility Public.
