Hi,
 
I've a question about ares DNS resolver code.
 
As UDP is not a connection oriented protocol the quires may or may not reach the name servers
in the first attempt itself .
 
Unlike the present ares code, to overcome this situation ares stack has to take care right?
Like ares may be retransmit the queries in Exponential back-off or the application which is using the
ares stack has to take care this kind of re-transmission?
 
Please clarify,
 
Thanks in advance,
Bharath
