In CentOS 7, there are a couple of straightforward methods to find the IP address of your system. This information can be vital for network troubleshooting or system administration tasks. Below, we’ll cover two common approaches: using the ip command and the ifconfig command.
Using the ip Command
The ip command is the modern replacement for ifconfig and provides more detailed network information. Here’s how you can use it to find your IP address:
Open a terminal on your CentOS 7 system.
Run the following command:

Verifying IP Address
In both cases, look for the line labeled inet followed by your IP address. Typically, it will look like inet XXX.XXX.XXX.XXX, where XXX.XXX.XXX.XXX is your IP address.
By following these steps, you can quickly identify the IP address of your CentOS 7 system using either the ip or ifconfig command. Understanding your system’s network configuration is fundamental for effective system administration and troubleshooting.
