To find your IP address in Linux, one of the most commonly used commands is `ifconfig`. This tool provides detailed information about your network interfaces.
Simply type `ifconfig` in the terminal. Hit enter, and you’ll see a list of all active network interfaces on your system. Each interface will have its own section displaying various details.
Look for sections labeled like “eth0,” “wlan0,” or similar names based on whether you’re connected via Ethernet or Wi-Fi. The lines under each section contain important data.
Your specific IP address appears next to “inet addr” (for IPv4) or just “inet” depending on the version of ifconfig you’re using. Note that this command may not be installed by default in some distributions, so keep that in mind if it doesn’t respond as expected.
Step 3: Identifying Your IP Address
Once you’ve run the ifconfig command, it’s time to identify your IP address. Look for the section labeled “inet” under the network interface you are using, typically named eth0 or wlan0. This information is essential for understanding your connection.
The number next to “inet” represents your IPv4 address. It usually follows a format like 192.168.x.x or 10.x.x.x, which indicates a private IP address commonly used in local networks.
If you’re on a public network, this may also show an external IP depending on your configuration. Always double-check that you’ve located the correct interface; sometimes there can be multiple listings if you’re connected through different methods.
Take note of any other related addresses as well—such as subnet mask and broadcast address—as they provide additional context about your network setup.
Different Methods to Find IP Address in Linux
When it comes to checking IP adress in Linux, you have several methods at your disposal. Each method caters to different user preferences and needs.
