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 3 announced prefixes have no ROA (RPKI not found): 192.190.204.0/24, 192.190.205.0/24, 192.231.170.0/24.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS59326 and a max length equal to the prefix length:

    192.190.204.0/24 AS59326 max-length /24
192.190.205.0/24 AS59326 max-length /24
192.231.170.0/24 AS59326 max-length /24

    Fix: Try again in a minute.
