    <p>Have you tried listing the destinations on the same line, <a
        moz-do-not-send="true"
        href="https://docs.powerdns.com/recursor/settings.html#forward-zones">separated
        by semicolons</a>?<br>
    </p>
    <p>forward-zones+=some.domain.tld=AUTH1_ipv6;AUTH1_ipv4;AUTH2_ipv6;...etc</p>
    <p>Personally I would use forward-zones-file to make this cleaner. 
      Also, I wouldn't forward to both ipv4 and ipv6 on the same server;
      if the server is down, it's going to be unreachable via both.<br>
