If you are getting this assigned by DHCP from your router, it can be
controlled with /etc/dhclient.conf. Typically most of the settings do not
require alteration, but maybe an item or two needs a tweak. Placing these
into dhclient.conf can either override or adjust, as needed.

This is an example from my pf/gateway box which gets all it's external NIC
settings by DHCP from my DSL modem. I wanted this box to use it's own DNS
server, as do the other boxen on the LAN, instead of the one in the DSL
modem.

interface "rl0" {
        send dhcp-client-identifier 00:0e:2e:6d:17:54;
        prepend domain-name-servers 127.0.0.1;

}

There are many other settings, man dhclient.conf and man dhcp-options for
more details.
