What commands will tell us what our IP address is on our Linux system?

The commands that are designed to display information about network interfaces and their configurations on a Linux system include "ip addr show" and "ifconfig."

Using "ip addr show," a user can view the current IP address assigned to the network interfaces on the system. This command provides detailed information, including the interface name, its status, and its current IP addresses.

"ifconfig," though older and now superseded in many use cases by the "ip" command, still functions on many systems to show similar details. It provides the IP address, netmask, and broadcast address for each interface. Hence, both commands effectively serve the purpose of revealing the system's IP address, making this choice the right one for identifying the IP address on a Linux system.

In contrast, the other sets of commands are intended for different purposes. Ping and traceroute are typically used for testing connectivity and network paths rather than displaying IP configurations. Netstat and ss are primarily used for viewing network connections and sockets rather than interface configurations. Lastly, ifup and ifdown are commands used to activate or deactivate network interfaces respectively, and do not provide information about the current IP address.
