Hi<br>
<br>
AAAA record should be used first if present. But if there&#39;s an a A and AAAA then both should be used too , ie in client or proxy mode - we have dual stack and gave both v6 and v4 defined to give us routing resiliency<br>
<br>
Also... if the address doesn&#39;t resolve the server fails to start? Ouch.  Very nasty behaviour -1 <br>
