What does the 'ifconfig' command do?

The 'ifconfig' command is primarily used for network interface configuration in Unix-like operating systems. When executed, it provides information about the current state and configuration of network interfaces on the system. This includes details such as the IP address assigned to each interface, the subnet mask, the MAC address, and statistics related to data transmission and errors.

Being a fundamental tool for network management, 'ifconfig' allows users to enable or disable interfaces, set IP addresses, and configure other network settings as necessary. Given its role in managing and displaying information about network interfaces, the option related to displaying network interface configuration is the correct and most relevant choice.
