-iface eth0 inet dhcp</code>
-  * Static Setup Example<code bash>auto eth0

-  netmask 255.255.255.0
-  gateway 192.168.0.254
-  dns-nameservers 8.8.8.8 8.8.4.4</code>
-  * Bring the interface up (if brought down at the start)<code bash>ifup eth0</code>
-  * Otherwise, restart to fix nameserver conflicts between dhclient and static.<code bash>shutdown -r now</code>
