What to fix

  1. Warning

    6 of 6 announced prefixes have no ROA (RPKI not found): 23.153.224.0/24, 142.249.32.0/23, 172.81.38.0/23, 172.81.38.0/24, 172.81.39.0/24 (+1).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS397095 and a max length equal to the prefix length:

    23.153.224.0/24 AS397095 max-length /24
142.249.32.0/23 AS397095 max-length /23
172.81.38.0/23 AS397095 max-length /23
172.81.38.0/24 AS397095 max-length /24
172.81.39.0/24 AS397095 max-length /24
2602:fe34::/36 AS397095 max-length /36

    Open in RPKI / ROA validator Guide

  2. Warning

    1 of 6 announced prefixes have no IRR route object: 2602:fe34::/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 AS397095 in your RIR’s IRR database (or RADB).

    route6: 2602:fe34::/36
origin: AS397095

  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.
