What Windows command-line utility displays current TCP/IP configurations?

• A. Ipconfig
• B. Ping
• C. Netstat
• D. Tracert

Answer: (A)

This question focuses on how to view the machine’s current TCP/IP configuration in Windows. Ipconfig is the Windows command-line utility designed for this purpose. It shows the IP address, subnet mask, and default gateway for each network interface, and when you use the /all switch it reveals additional details like DNS servers, DHCP status, lease information, MAC addresses, and more. This makes it ideal for quickly confirming what IP the computer has, which network it’s on, and whether DHCP has assigned an address.

Other common commands serve different tasks: Ping tests connectivity to another host, Netstat lists active connections and port information, and Tracert shows the path packets take to a destination. None of these display the local TCP/IP configuration in detail the way ipconfig does.
