What to fix

  1. Warning

    10 of 40 announced prefixes have no ROA (RPKI not found): 23.165.224.0/22, 23.165.224.0/23, 23.165.226.0/23, 44.4.41.0/24, 199.19.152.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS26073 and a max length equal to the prefix length:

    23.165.224.0/22 AS26073 max-length /22
23.165.224.0/23 AS26073 max-length /23
23.165.226.0/23 AS26073 max-length /23
44.4.41.0/24 AS26073 max-length /24
199.19.152.0/24 AS26073 max-length /24
199.19.153.0/24 AS26073 max-length /24
199.255.16.0/24 AS26073 max-length /24
199.255.18.0/24 AS26073 max-length /24
199.255.19.0/24 AS26073 max-length /24
208.80.44.0/22 AS26073 max-length /22

  2. Warning

    15 of 40 announced prefixes have no IRR route object: 2606:45c0:50::/44, 2602:fe19:10::/48, 2602:fe19:4002::/48, 2602:fe19:4016::/48, 2606:7940:30::/44 (+10).

    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 AS26073 in your RIR’s IRR database (or RADB).

    route6: 2606:45c0:50::/44
origin: AS26073

route6: 2602:fe19:10::/48
origin: AS26073

route6: 2602:fe19:4002::/48
origin: AS26073

  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.
