Step-by-step explanation:
A /all switch is most likely to be used with the ipconfig command. This command is used in Microsoft Windows to display all current TCP/IP network configuration values and refresh Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. Using the /all switch with ipconfig provides a detailed information output, including the hostname, primary DNS suffix, node type, IP routing enabled, WINS Proxy enabled, and the list of all IP addresses with their respective subnets and default gateways.
