Change Ubuntu Server IP Address – Step-by-Step Guide with Pros and Cons

Introduction

Greetings readers! Are you tired of facing network issues due to your Ubuntu server’s IP address? Changing the IP address of your Ubuntu server can be a little daunting, but it’s a necessary task to maintain a stable network environment. In this article, we will guide you through the process of changing your Ubuntu server IP address and discuss its advantages and disadvantages.

Firstly, we need to understand the basics of an IP address. An IP address is a unique numerical identifier that is assigned to every device that is connected to a network. It serves as an address that enables devices to communicate with each other. There are two types of IP addresses: static and dynamic. A static IP address is a permanent IP address that is manually assigned to a device, whereas a dynamic IP address is a temporary address that is automatically assigned by a DHCP (Dynamic Host Configuration Protocol) server.

Now, let’s move ahead and understand the process of changing the IP address of your Ubuntu server.

Step-by-Step Guide

Follow these simple steps to change your Ubuntu server IP address:

1. Open Terminal

   The first step is to open the Terminal on your Ubuntu server. You can do this by pressing the Ctrl+Alt+T shortcut key or by typing “Terminal” in the search bar.

2. Edit Network Interfaces File

   Once you have opened the Terminal, you need to edit the network interfaces file. Type the following command in the Terminal:

   sudo nano /etc/network/interfaces

   This will open the interfaces file in the Nano text editor.

3. Locate Current IP Address

   You will see your current IP address in the interfaces file. Locate the line that says “address [current IP address]”.

4. Edit IP Address

   Replace the current IP address with the new IP address that you want to set for your Ubuntu server. Make sure to use a unique IP address that is not already assigned to any other device on the network.

5. Configure Gateway Address

   You also need to configure the gateway address. Locate the line that says “gateway [current gateway address]”. Replace the current gateway address with the new gateway address.

6. Save and Exit

   Once you have made the necessary changes, press Ctrl+O to save the file and Ctrl+X to exit Nano.
