You're debugging a computer that can't resolve domain names to IP addresses. What command-line utility can help determining which DNS server the device uses?

The nslookup utility will query the DNS server that is currently set up on the computer. The utility can be used to do various DNS queries. The netstat command displays the number of TCP connections and their port numbers on a computer. The ping command is used to determine whether or not a remote device is connected. When entered as ping localhost, it is used to determine whether TCP/IP is running on the local device. The tracert shows the routing path that a packet followed to reach a remote computer.
