   Hello Tim,

   Ouch! I have been playing around with IPv6 for well over a decade and I say WP   
   is definitely NOT following common practice. Common practice is that when the   
   host name resolves to both an IPv4 and an IPv6 address to try IPv6 first and   
   when that fails to try IPv4.   
      
   Maybe we should discuss this in the IPv6 echo. You are welcome to join there,   
   it is available from your Boss node.   
      
      
   Cheers, Michiel
