How to setup a static IP address on Ubuntu 16 LTS

In this quick tutorial i’m gonna explain how to setup a static IP address on ubuntu 16 LTS, the file which we need to make some changes is /etc/network/interfaces.

For this tutorial, we’re going to assign to my server these entries:
– IP address : 192.168.1.10
– NetMask 255.255.255.0
– Gateway 192.168.1.1
– Domain Name Servers : 192.168.1.2 192.168.1.3

First let’s open the file:

[root@server ~]# vim /etc/network/interfaces

 

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto enp0s3
iface enp0s3 inet dhcp

 
Here we need to remove or comment iface enp0s3 inet dhcp or change it to static then add the static ip address, netmask, gateway and the dns servers like below :

# The primary network interface
auto enp0s3
#iface enp0s3 inet dhcp
iface enp0s3 inet static
address 192.168.1.10
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 192.168.1.2 192.168.1.3

 

Next, save the file and reboot the networking service .

[root@server ~]# systemctl restart networking

 
or this command

[root@server ~]#/etc/init.d/networking restart

 
Until the next time.
