If you do not use ifupdown, you need to edit /etc/dhcp3/dhclient.conf

Find the lines 

#prepend domain-name-servers 127.0.0.1;
request subnet-mask, broadcast-address, time-offset, routers,
        domain-name, domain-name-servers, host-name,
        netbios-name-servers, netbios-scope;

And change them to 

prepend domain-name-servers 1.2.3.4, 1.2.3.5;
request subnet-mask, broadcast-address, time-offset, routers,
        domain-name, host-name,
        netbios-name-servers, netbios-scope;

Replace 1.2.3.4 and 1.2.3.5 with the addresses of your DNS servers.

Run 

sudo invoke-rc.d networking restart
