  	    <td class='clDescription'>The default address of :: was being bound, but on servers which do not have ipv6 modules installed, this will cause crashes. We need a solution to 
  1) detect if ipv6 is supported. 
  2) select bind_address of 0.0.0.0 if it is not
  3) select bind_address of :: if it is
  Additional fix should be that this change is hard coding an address here making it not possible for configuration to override this setting. Both of these issues should be resolved with teh defautls change.  </td>
