Common mistakes.
- A. The ifconfig (or ipconfig on Windows) command displays network interface configuration such as IP address and subnet mask, not active network connections.
- B. The nslookup command queries DNS servers to resolve hostnames to IP addresses and provides no information about active TCP/IP connections.
- D. The arp command displays and manages the ARP cache, which maps IP addresses to MAC addresses, and does not show TCP connection states or port usage.
