What to fix

  1. Warning

    4 of 235 announced prefixes have no ROA (RPKI not found): 2404:efc0:141::/48, 2404:efc0:142::/48, 2404:efc0:143::/48, 2404:efc0::/32.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS10122 and a max length equal to the prefix length:

    2404:efc0:141::/48 AS10122 max-length /48
2404:efc0:142::/48 AS10122 max-length /48
2404:efc0:143::/48 AS10122 max-length /48
2404:efc0::/32 AS10122 max-length /32

    Open in RPKI / ROA validator Guide

  2. Warning

    4 of 235 announced prefixes have no IRR route object: 2404:efc0:142::/48, 2404:efc0::/32, 2404:efc0:141::/48, 2404:efc0:143::/48.

    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 AS10122 in your RIR’s IRR database (or RADB).

    route6: 2404:efc0:142::/48
origin: AS10122

route6: 2404:efc0::/32
origin: AS10122

route6: 2404:efc0:141::/48
origin: AS10122

  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.
