[Dnsmasq-discuss] DNS search Order

Hello,

I was wondering how does DNSMASQ use the DNS servers that it knows about.

If "strict-order" is enabled, it uses them in the order found in the  
dnsmasq.conf file. If the first server doesn't reply, or can't answer,  
then it goes and tries the next one and so on.

But if "strict-order" isn't enabled. How does DNSMASQ know which  
server(s) to contact? Does it use them all all the time? If not how  
does it determine which server to contact?
How long does an entry in the cache remain valid before it checks again?

thank you

Philippe
