Fedora Linux is a free, open-source Linux distribution backed by Red Hat. The IP address of a network adapter is its location on the Internet. Other computers need your IP address to connect to your Fedora Linux system. Fedora includes the "Network Manager," which manages active network adapters and provides a graphical tool for viewing their information and IP addresses, as well as standard Linux command line tools for doing the same.
Right-click the "Network Manager" icon displaying two computers in the notification area at the upper-right corner of your desktop.
Click "Connection Information" in the menu that appears.
Read the IP address to the right of "IP Address" under "Active Network Connections." Click the tabs at the top of the window to view other network adapter's IP addresses, if you have more than one installed.
Open a Terminal by clicking "Applications," "System Tools" and "Terminal."
Type "/sbin/ifconfig" into the "Terminal" window and press "Enter."
Read the IP address of each network adapter to the right of "inet addr:" in the "Terminal" window. "127.0.0.1" under "lo" is the local network address of the computer and not its IP address.
