Find IP address in Linux Operating System

Hi Anonymous, hope the following steps will guide you in fixing this issue.:..:

–> As you said that you are one of the users of the Linux to know your systems IP address or other information related to the network first thing is the users must have the administrator privileges.

–> If you are utilizing a GUI interface for your Linux/Unix machine then you need to just open the Linux/Unix shell In the prompt that you had opened type as "ifconfig eth0 " excluding quotes and then press enter hence this results in the listing of the information that is related to the network.

–> Generally users see commonly the network settings available for all their network devices when we run the "ipconfig" command.

–> For Home network/corporate network users the information is the IP address of your computer in your network and If your computer gets connected to the Internet automatically the IP address is more likely which not be the IP address of the other people and web pages see. 

Thank you.. 🙂
