What to fix

  1. Warning

    10 of 60 announced prefixes have no ROA (RPKI not found): 64.21.0.0/17, 64.21.128.0/19, 64.21.160.0/20, 64.21.176.0/21, 64.247.0.0/18 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS8001 and a max length equal to the prefix length:

    64.21.0.0/17 AS8001 max-length /17
64.21.128.0/19 AS8001 max-length /19
64.21.160.0/20 AS8001 max-length /20
64.21.176.0/21 AS8001 max-length /21
64.247.0.0/18 AS8001 max-length /18
64.247.12.0/24 AS8001 max-length /24
66.29.0.0/17 AS8001 max-length /17
66.29.98.0/24 AS8001 max-length /24
66.104.102.0/24 AS8001 max-length /24
66.246.0.0/16 AS8001 max-length /16

  2. Warning

    34 of 60 announced prefixes have no IRR route object: 216.69.213.0/24, 70.47.50.0/23, 207.192.76.0/24, 70.47.54.0/24, 2001:518:2802::/48 (+29).

    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 AS8001 in your RIR’s IRR database (or RADB).

    route: 216.69.213.0/24
origin: AS8001

route: 70.47.50.0/23
origin: AS8001

route: 207.192.76.0/24
origin: AS8001

  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.
