What to fix

  1. Problem

    2 of 134 announced prefixes are RPKI invalid: 45.158.17.0/24, 95.85.183.0/24.

    A ROA covers them but does not allow this origin or prefix length, so networks that filter (most large ones do) drop these routes.

    Fix: Fix the ROAs (origin AS and max length) at your RIR, or stop announcing the routes.

    Open in RPKI / ROA validator Guide

  2. Warning

    1 of 134 announced prefixes have no ROA (RPKI not found): 185.50.184.0/22.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS41897 and a max length equal to the prefix length:

    185.50.184.0/22 AS41897 max-length /22

    Open in RPKI / ROA validator Guide

  3. Warning

    4 of 134 announced prefixes have no IRR route object: 2a00:ad07:3000::/36, 46.40.16.0/23, 46.40.43.0/24, 2a00:ad00:2010::/44.

    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 AS41897 in your RIR’s IRR database (or RADB).

    route6: 2a00:ad07:3000::/36
origin: AS41897

route: 46.40.16.0/23
origin: AS41897

route: 46.40.43.0/24
origin: AS41897

  4. Warning

    No IRR as-set is listed.

    Peers and route servers build prefix filters from the as-set. Without one they fall back to the AS number alone, which breaks as soon as you have customers.

    Fix: Create an as-set in your RIR’s IRR database and add it to your PeeringDB record.

  5. 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.
