A computer’s IP address is its unique codename, identifying it within a network and acting like a postal address for the machine. This allows it to communicate with other computers, servers, or devices over a network connection and ensures that network traffic is sent to the correct destination. In this article, we will take a look at how to check the IP address of a Linux computer using a variety of different commands. To do this, you will need to open a terminal window/command line. Once you have done this, the system will display your internal IP address. This will include entries for your wired (Ethernet) and wireless (Wi-Fi) adapters, if you have them installed. Depending on your operating system, this may also include an entry for a virtual adapter that is used solely by your operating system.
There are two main types of IP addresses; public and private. A private IP address identifies the device within a specific network or internet connection, and cannot be accessed from anywhere else. A public IP address, on the other hand, is a unique identifier that can be accessed from any network around the world. The ip command is an extremely powerful tool that can help you find the IP address of any device on your Linux system. It is shipped by default with all modern Linux distributions and can be found in the man pages.
To find your private IP address in Ubuntu, click on the cog icon or the settings menu, then select “Network”. You should see a list of network connections, with your Wi-Fi and Ethernet connections shown as active. Then, click on the arrow next to your network connection and you should see your IP address listed.
You can also use the ip addr command to view your IP address on Linux, but this will display both your loopback address (127.0.0.1) and your actual private IP address, so you will need to filter out the results. This method is useful if you want to be able to view your IP address from the command line without having to utilize external third party tools.
Another way to view your IP address in Ubuntu is to use the ip route command, which will show you all of the routes that are currently configured for your networking interfaces (wired and wireless). This will allow you to quickly identify any public/private IP addresses that might be allocated by DHCP on your network interfaces.
With a little knowledge of the ip command, it is easy to get your computer’s internal IP address in Linux. This information can be invaluable in troubleshooting connectivity issues and can help you keep track of your computer’s status on your network. Whether you are just learning how to navigate your Linux system or are a seasoned IT professional, the ip command is a valuable tool for any administrator’s arsenal.
