What to fix

  1. Warning

    10 of 137 announced prefixes have no ROA (RPKI not found): 38.81.194.0/24, 38.81.195.0/24, 45.43.5.0/24, 45.43.28.0/24, 66.36.233.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS29838 and a max length equal to the prefix length:

    38.81.194.0/24 AS29838 max-length /24
38.81.195.0/24 AS29838 max-length /24
45.43.5.0/24 AS29838 max-length /24
45.43.28.0/24 AS29838 max-length /24
66.36.233.0/24 AS29838 max-length /24
66.45.105.0/24 AS29838 max-length /24
66.178.176.0/20 AS29838 max-length /20
66.231.176.0/20 AS29838 max-length /20

66.231.180.0/22 AS29838 max-length /22

  2. Warning

    79 of 137 announced prefixes have no IRR route object: 67.208.88.0/22, 69.169.24.0/21, 38.81.195.0/24, 2607:f108:1800::/40, 205.251.108.0/22 (+74).

    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 AS29838 in your RIR’s IRR database (or RADB).

    route: 67.208.88.0/22
origin: AS29838

route: 69.169.24.0/21
origin: AS29838

route: 38.81.195.0/24
origin: AS29838

  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.
