WHAT IS STATIC IP ADDRESS ? HOW TO CONFIGURE STATIC IP ADDRESS IN UBUNTU 16.04

Introduction
In this article we are going to learn How to configure static IP address in Ubuntu 16.04. Before start the configuration let’s understand what is Static IP address. There are two ways by which we can configure IP address. One is Static IP address and another one is Dynamic IP address. When we manually configure the IP address for any network device is called as Static IP address and when DHCP Server assigns IP address to network devices automatically is called as Dynamic IP address. Normally we assign’s Static IP address to network devices like Router, Switch, to any Server, Network printer and so on.

Follow the below steps to configure static ip address in Ubuntu 16.04
There are two method’s by which we can configure Static IP address and both methods are simple to follow. Here in this article I will explain both methods. So let’s get started.
Method : 1
First to check your available network interfaces use the below command.

elinuxbook@ubuntu:~$ ifconfig # Check Network Interfaces

This method we have to do using terminal. So to configure Static IP address we have to edit a configuration file named interfaces. The location of this file is /etc/network/interfaces. So post editing the file using your preferred text editor you have to enter all the details i.e. IP Address, Subnet Mask, Gateway Address and DNS Servers manually. Here the name of my Network Interface is ens33. Refer the command below.

Note : The configuration part highlighted in Yellow color.
elinuxbook@ubuntu:~$ sudo nano /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto ens33
iface ens33 inet static
address 192.168.1.50
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 192.168.1.100 192.168.1.101

After configuring the IP address by following above steps you have to refresh the settings by flush the Network Interface using below command.

elinuxbook@ubuntu:~$ sudo ip addr flush ens33

Now restart the Networking Service to take effect the changes using below command.
elinuxbook@ubuntu:~$ sudo systemctl restart networking.service

Now we are Done. To check the configured Static IP address refer the below command.
elinuxbook@ubuntu:~$ ifconfig ens33
ens33 Link encap:Ethernet HWaddr 00:0c:29:ff:cd:2e
inet addr:192.168.1.50 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:4833 errors:0 dropped:0 overruns:0 frame:0
TX packets:3446 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:6985228 (6.9 MB) TX bytes:292627 (292.6 KB)

Method : 2

Now let’s have a look at Graphical way of static IP Address configuration. This step is quiet simple to follow and easy way to configure IP address. So to configure the IP address in graphical way just click on Search Box on your Ubuntu 16.04 and Search for Network Connection. Refer the snapshot below.
