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

    7 of 12 announced prefixes have no IRR route object: 213.163.208.0/21, 213.163.216.0/21, 195.181.188.0/22, 31.15.76.0/24, 195.181.184.0/22 (+2).

    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 AS44513 in your RIR’s IRR database (or RADB).
