What to fix

  1. Warning

    10 of 59 announced prefixes have no ROA (RPKI not found): 170.238.4.0/22, 170.238.4.0/23, 170.238.4.0/24, 170.238.5.0/24, 170.238.6.0/23 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS61928 and a max length equal to the prefix length:

    170.238.4.0/22 AS61928 max-length /22
170.238.4.0/23 AS61928 max-length /23
170.238.4.0/24 AS61928 max-length /24
170.238.5.0/24 AS61928 max-length /24
170.238.6.0/23 AS61928 max-length /23
170.238.6.0/24 AS61928 max-length /24
170.238.7.0/24 AS61928 max-length /24
200.12.0.0/20 AS61928 max-length /20
200.12.0.0/21 AS61928 max-length /21
200.12.0.0/22 AS61928 max-length /22

  2. Warning

    20 of 59 announced prefixes have no IRR route object: 2804:184c::/36, 2804:184c:f000::/36, 2804:184c:6000::/36, 2804:184c:8000::/34, 2804:184c:7000::/36 (+15).

    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 AS61928 in your RIR’s IRR database (or RADB).

    route6: 2804:184c::/36
origin: AS61928

route6: 2804:184c:f000::/36
origin: AS61928

route6: 2804:184c:6000::/36
origin: AS61928

  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.
