The usual place to enter the DNS server addresses is in the file 
/etc/resolv.conf . This file has a man page you can consult for the 
details, but the simplest version just has lines like these:

         nameserver 192.168.1.40
         nameserver 192.168.1.2

Some configuration tools will modify or overwrite this file, and DHCP 
clients can modify it if they get DNS-server info as part of a lease ... so 
there are distro-specific and site-specific elements to this question.
