Three ways to change the IP address in Linux

1. To change the IP address using the command line: In a Linux system, you can use the ifconfig command to modify the IP address of a network interface. For example, use the following command to change the IP address to 192.168.0.100:

Set the IP address of eth0 to 192.168.0.100 using ifconfig.

1. Change the IP address using a network management tool: Most Linux distributions provide network management tools such as Network Manager or Netplan. These tools offer graphical or command-line interfaces for easily changing the IP address. For example, in Ubuntu, you can use the following command to change the IP address:

execute netplan apply with administrative privileges

1. Editing the network configuration file to change the IP address is another way to change the IP address directly. In most Linux distributions, the network configuration file is located in either /etc/network/interfaces or /etc/sysconfig/network-scripts/ directory. By editing these files, you can manually change the IP address. For example, in Ubuntu, you can use the following command to edit the network configuration file:

open the file 01-netcfg.yaml in the /etc/netplan directory using the text editor nano with sudo permissions

Next, update the relevant IP address and save the file. Finally, use the following command to apply the changes:

Execute the netplan apply command with elevated privileges.
