What to fix

  1. Problem

    9 of 154 announced prefixes are RPKI invalid: 79.182.32.0/24, 79.182.52.0/24, 79.182.75.0/24, 79.182.76.0/24, 79.182.123.0/24 (+4).

    A ROA covers them but does not allow this origin or prefix length, so networks that filter (most large ones do) drop these routes.

    Fix: Fix the ROAs (origin AS and max length) at your RIR, or stop announcing the routes.

    Open in RPKI / ROA validator Guide

  2. Warning

    1 of 154 announced prefixes have no ROA (RPKI not found): 61.100.38.0/24.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS214432 and a max length equal to the prefix length:

    61.100.38.0/24 AS214432 max-length /24

    Open in RPKI / ROA validator Guide

  3. Warning

    9 of 154 announced prefixes have no IRR route object: 192.217.238.0/24, 2001:978:b01::/48, 207.152.104.0/24, 199.234.72.0/24, 207.152.105.0/24 (+4).

    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 AS214432 in your RIR’s IRR database (or RADB).

    route: 192.217.238.0/24
origin: AS214432

route6: 2001:978:b01::/48
origin: AS214432

route: 207.152.104.0/24
origin: AS214432

  4. 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.
