What to fix

  1. Warning

    10 of 33 announced prefixes have no ROA (RPKI not found): 91.217.58.0/23, 129.185.30.0/24, 129.185.31.0/24, 129.185.32.0/24, 129.185.33.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS6 and a max length equal to the prefix length:

    91.217.58.0/23 AS6 max-length /23
129.185.30.0/24 AS6 max-length /24
129.185.31.0/24 AS6 max-length /24
129.185.32.0/24 AS6 max-length /24
129.185.33.0/24 AS6 max-length /24
129.185.34.0/24 AS6 max-length /24
129.185.35.0/24 AS6 max-length /24
141.112.0.0/16 AS6 max-length /16
141.112.0.0/18 AS6 max-length /18
192.5.32.0/24 AS6 max-length /24

  2. Warning

    3 of 33 announced prefixes have no IRR route object: 192.5.32.0/24, 91.217.58.0/23, 192.90.136.0/24.

    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 AS6 in your RIR’s IRR database (or RADB).

    route: 192.5.32.0/24
origin: AS6

route: 91.217.58.0/23
origin: AS6

route: 192.90.136.0/24
origin: AS6

  3. 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.

  4. 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.
