It depends on whether you are using pump or dhcpd. I will assume pump, I think 
that is the default. 

You need to add --no-dns to the call to "pump". Sounds easy. But the call to 
pump is made from ifup, which is invoked from the script 
/etc/init.d/networking. Therefore to make the fix you need to talk to pump 
directly. You do this by creating a new file, /etc/pump.conf. It should 
contain the following:

device eth0 {
    nodns
}

That is, assuming that your ISP is through eth0. Look at the man page for pump 
for more information, under the section CONFIG_FILE.
