Ubuntu Server 14.04 How To Change IP Address From Dynamic To Static

When setting up a server, it is more practical to set the IP Address to Static or Fixed IP Address

To view and change your IP Address type:

  $ sudo nano /etc/network/interfaces  

If your primary network interface (usually eth0) is dynamic it will display these lines:

  #The primary network interface
 auto eth0                                    
 iface eth0 inet dhcp                      

To change it to static IP Address change 'dhcp' to 'static' and enter the rest of the data below:

#The primary network interface
auto eth0
iface eth0 inet static
address 192.168.0.254
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1

For nano^* editor press ctrl-X and the press 'Y' and Enter.

This is assuming that you are using the following data:

• subnet 192.168.0.x 
• IP address of your server:  192,168,0,254
• Gateway: 192.168.0.1

To implement the changes, you need to restart the network card (eth0). You do this by disabling the eth0 and enabling it again, type the two commands below.

$sudo ifdown eth0 

$sudo ifup eth0  

To verify if the new configuration is used type:

 $ifconfig 

You're supposed to see the IP address you have entered above.
