What to fix

  1. Warning

    2 of 5 announced prefixes have no ROA (RPKI not found): 38.172.195.0/24, 44.30.174.0/24.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS214331 and a max length equal to the prefix length:

    38.172.195.0/24 AS214331 max-length /24
44.30.174.0/24 AS214331 max-length /24

    Open in RPKI / ROA validator Guide

  2. 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.
