Which command could provide information about IP addressing of all interfaces, including status and hardware addresses?

The command that provides information about IP addressing for all interfaces, including their statuses and hardware addresses, is indeed the one that starts with "show ip interface brief." This command summarizes the interface status and address information in a concise format. It displays details such as the IP address assigned to each interface, whether the interface is up or down, and the corresponding MAC (hardware) addresses.

This command is especially valuable for network administrators who need a quick overview of the current state of the network interfaces without the overwhelming details that might come from other commands. It allows easy troubleshooting and monitoring of a device's interface configurations at a glance.

In contrast, the other options serve different purposes. While "show interfaces" provides detailed information about each interface, including statistics and configurations, it does not summarize in the same straightforward manner. "Show ip route" focuses on the routing table rather than interface details, and "show config" displays the entire device configuration, which is much broader than just interface information.
