What command retrieves the complete MAC address information on a Windows device?

The command that retrieves the complete MAC address information on a Windows device is "ipconfig /all." This command provides a detailed overview of all network interfaces and their configurations, including IP addresses, subnet masks, default gateways, and the physical MAC address of each network adapter. When executed in the Command Prompt, it displays not only the MAC address but also additional network-related information, making it a comprehensive tool for troubleshooting and diagnosing network issues.

While other options may reference commands that relate to network configurations, they do not provide the complete MAC address information in the detailed format that "ipconfig /all" does. For example, "get mac address" is not a valid command in Windows, and "show mac address" is more applicable to Cisco devices in their command-line interface rather than Windows. The "arp -a" command displays the Address Resolution Protocol table, which includes IP address to MAC address mappings, but it does not present the MAC address information for all network interfaces in the same detailed manner as "ipconfig /all." Thus, "ipconfig /all" is the appropriate choice for retrieving comprehensive MAC address information on a Windows device.
