[rabbitmq-discuss] shovel ipv6 resolving dns name

Hi, 

I set up a test shovel which shovels messages from New York to LA. When I use ipv6 ipaddresses the shovel works. If I exchange the ipv6 addresses with the actual  DNS name it fails. It seems to connect to the ipv4 address first and then just fails. The error msg I get is: 

"{{badmatch,{error,econnrefused}},
 [{rabbit_shovel_worker,make_conn_and_chan,1},
  {rabbit_shovel_worker,handle_cast,2},
  {gen_server2,handle_msg,2},
  {proc_lib,init_p_do_apply,3}]}
"

Is there an erlang kernel option the say go ipv6 first?
