both ipv4 and ipv6. when dhcp clients getting the ipv4 and ipv6 both 
everything is working fine,but when clients is getting only the ipv6 
it's not getting resolve the name but it's going out via ip address.i 
hope something i mess up here.please help me what i want to do here.

#log-facility local7;
subnet6 2404:1f00:31:31::/64 {
         # Range for clients
         range6 2404:1f00:31:31::2 2404:1f00:31:31::254;
         # Additional options
