Set A Static IP On Ubuntu

This article will guide you on how to set a static IP address on Ubuntu. This guide applies to all version of Ubuntu and Ubuntu Server.

Everything you need to set up is in the /etc/network/interfaces file. Use your favorite editor (for example VIM) to edit the file:

sudo vi /etc/network/interfaces

Then, you should see something like this:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

The key here is to change the last 2 lines. The last 2 lines tells the DHCP server to get an IP automatically. To configure properly your static IP, first run the ifconfig command to find out your current configuration:


This will give you everything you need to configure properly your static IP. Now that you have everything, you will need to remove or comment the following lines of the /etc/network/interfaces:

#auto eth0
#iface eth0 inet dhcp

And add these lines with your own configuration:

auto eth0
iface eth0 inet static

If you prefer to set up the nameserver somewhere else, you can also put the nameserver configuration in the /etc/resolvconf/resolv.conf.d/base file, by adding this line:

nameserver 192.168.1.XXX

Regenerate the resolv.conf:

sudo resolvconf -u

Remove the DHCP client:

sudo apt-get remove dhcp-client

Restart network service:

sudo /etc/init.d/networking restart
