You do not have to configure anything at all for a basic DHCP client 
to be able to function - that is the whole point of DHCP. In the 
absence of a config that says otherwise, the client will simply get 
and process a default set of options - eg it will ask for basic 
network parameters (address, mask, gateway, DNS servers) and 
configure the network and resolver accordingly.
