How can you view the settings and status of network interfaces?

The command that allows you to view the settings and status of network interfaces is ip addr show. This command is part of the iproute2 package, which is the modern utility set for managing networking on Linux systems. When executed, it provides detailed information about all network interfaces, including their IP addresses, network masks, link status, and other relevant details. This output helps system administrators understand the current configuration and status of each interface.

While other commands mentioned have their own purposes, they do not provide as comprehensive a view specifically focused on network interface settings. For instance, ifconfig is an older command that can still show network interface information, but it is considered deprecated in favor of the ip command. The netstat -i command displays information about network interfaces and statistics but lacks detailed address information. The command route -n is used to display the routing table and does not display detailed information about each network interface. Thus, ip addr show stands out as the most versatile and detailed option for checking network interface settings.
