What to fix

  1. Warning

    No IRR as-set is listed.

    Peers and route servers build prefix filters from the as-set. Without one they fall back to the AS number alone, which breaks as soon as you have customers.

    Fix: Create an as-set in your RIR’s IRR database and add it to your PeeringDB record.

  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.
