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

    3 of 5 announced prefixes have no IRR route object: 217.21.38.0/24, 217.21.39.0/24, 178.172.150.0/24.

    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 AS49091 in your RIR’s IRR database (or RADB).

    route: 217.21.38.0/24
origin: AS49091

route: 217.21.39.0/24
origin: AS49091

route: 178.172.150.0/24
