Hi All,

Is anybody have idea about DNS Query handling by ares lib in IPv6 dual
stack scenario.

For Example -

If Preferred Network-IPv6 in Dual stack and Primary DNS Server-Ipv6
,Secondary DNS Server=Ipv4 then

1- Is DNS quad A query send first and if it is unsuccessful then Standard A
query send
                                      or
2- DNS Quad A Query and Standard A query send in parallel which is resolved
first .. will use accordingly .
