Change IP Address in Linux: Step-by-Step Guide

In Linux systems, the IP address can be modified using command line tools. Here are the steps to modify the IP address:

1. Open the Terminal window.
2. Use the following command to view the IP address and gateway information of the current network interface:

ifconfig

1. Edit the network interface configuration file using the following command (using eth0 as an example):

sudo nano /etc/network/interfaces

1. Locate the corresponding network interface configuration in the file (such as eth0) and make changes to the IP address, subnet mask, gateway, and other parameters.
2. Save the file and exit the editor.
3. Activate the new network configuration using the following command.

sudo systemctl restart networking

1. Use the following command to verify if the network interface configuration is effective:

ifconfig

By following the above steps, you can successfully change the IP address of your Linux system. Please note that changing the IP address may result in a network connection interruption, so it is recommended to backup important data before proceeding and to exercise caution.
