AAAA record should be used first if present. But if there'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>
Also... if the address doesn't resolve the server fails to start? Ouch. Very nasty behaviour -1 <br>
