$ ip [Options]

With the “-address” option, you can execute the “ip” command for listing the ip addresses associated with your network devices in this way:

$ ip addr

Here, we can find the IP address of our “enpos3” network device, which is “192.168.43.192”:

Now, to find your IP address in a Linux-based system, write out the “hostname” command with the “-I” option in your terminal:

$ hostname -I

How to find your IP Address in Linux using ifconfig command

ifconfig” is a network or system administration tool that permits you to manage, configure, and examine different network interface parameters using configuration scripts and terminals.
