[HowTo] Change Ubuntu IP Address from DHCP to Static

For those who are new to Ubuntu or Debian, default setting of your network card is using DHCP. And in some case you want to use static IP, maybe for bypass some filter or your DHCP server is not working properly then you cannot connect to the network unless your network administrator come and fix it. In that situation you really need to change your network configuration from dhcp to static ip.

To change your network configuration from dhcp to static ip is not hard. You can follow these steps below:

1. Open your terminal client
2. Type this command:

   sudo vim /etc/network/interfaces

3. Then you will see there are 2 network interface, lo and eth0. See example below:

   auto lo
   iface lo inet loopback
   
   auto eth0
   iface eth0 inet dhcp

4. Change the eth0 one according to your network setting (you can call your network administrator and tell you the setting) , see example below

   auto eth0
   iface eth0 inet static
   address 192.168.1.100
   netmask 255.255.255.0
   network 192.168.1.0
   broadcast 192.168.1.255
   gateway 192.168.1.1

5. Save that file and close
6. Restart your network to apply the new setting, with this command:

   /etc/init.d/networking restart

7. See your network configuration by type:

   ifconfig
