The answer is really simple. The DNS servers used are those listed in
/etc/resolv.conf

How they are used might be a little bit more complicated. Having more than
one DNS server listed in /etc/resolv.conf might be good for redundancy,
but it might also slow things down. For some reason it seems as if the
system waits for all servers to answer even if the first server gives a
correct answer.
