Final answer:
To view the DNS server address that a computer is using, you can use the ipconfig utility on Windows or the ifconfig utility on Linux.
Step-by-step explanation:
To view the DNS server address that a computer is using, you can use the ipconfig utility on Windows or the ifconfig utility on Linux. These utilities display network configuration details, including the DNS server address. On Windows, open the Command Prompt and type 'ipconfig /all' to see the DNS server address. On Linux, open the Terminal and type 'ifconfig' followed by the network interface name to see the DNS server address.
The nslookup and dig utilities are used to query DNS servers and retrieve information about domain names, but they do not display the DNS server address that the computer is using.
