An end-user has reported that they are unable to connect to the internet. After ensuring that the network cable is securely connected and the wireless switch is turned on, you decide to use a command-line tool to troubleshoot the local network adapter configuration and verify IP address settings. Which of the following commands would be the BEST to use for this purpose?
The ipconfig command displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. It can show the computer's IP address, subnet mask, and default gateway, making it the best initial choice for the scenario described. ping is used to test the reachability of a host on an IP network, tracert is for tracing the path that an IP packet takes to its destination, and hostname displays the current computer's name, none of which directly address the initial need to view local network adapter configuration.
