What to fix

  1. Warning

    No IPv6 prefixes announced.

    Networks without IPv6 force their users through NAT64 or leave them unreachable from IPv6-only networks.

    Fix: Get an IPv6 allocation from your RIR (usually free with your IPv4 membership) and announce it.

    Open in ASN & BGP prefix lookup

  2. 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.

  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.
