The default IP addresses and netmasks of the Ethernet ports are as
follows:

Configuring the Ethernet Interface
Linux users should follow these steps:
If you use the console cable to configure network settings for the first
time, use the following commands to edit the interfaces file. First, take all
network interfaces offline, before you reconfigure the LAN settings:
# ifdown –a
Next, edit the network interfaces file; you may use the text editor of your
choice, but VI is the default editor on the DA-681A-LX:
#vi /etc/network/interfaces
You may set the DA-681A for either dynamic IP addressing or static
addressing. To set it for dynamic IP addressing, enter the following lines
into the network interfaces file:
# The primary network interface
auto eth0
iface eth0 inet dhcp
