Yes it is there.

Except, when I configured  my interfaces, I use manual and
not dhcp because all the other machines' scripts are coded
to talk to this machine using pre-specified IP addresses.

During configuration, I specify the ip addresses of the machine,
the netmask, the gateway and the dns server and the search domain.
I do this for both the wireless and the wired.

This is also important because the router is programmed to route
certain incoming requests on certain ports to the specific IP address
of this machine.
