[Dnsmasq-discuss] "--all-servers" always on?

[John Siu]

Base on my understanding of the manpage, "all-servers" means dnsmasq will
send query to all servers at once and use the 1st response.

I am seeing all my queries, if not already in cache, are sent to all
servers configured. But I don't have "all-servers" set. I want to turn off
this behavior.
