Which command is traditionally used to display and configure network interfaces, though ip is the modern replacement?

• A. ip
• B. route
• C. ifconfig
• D. netstat

Answer: (C)

Historically, network interfaces were managed with ifconfig. It was the go-to tool for showing interface status and configuring parameters like IP addresses, netmask, and bringing interfaces up or down. Although the modern replacement is the ip command from iproute2, which unifies interface and routing management and adds broader IPv6 support and more features, the traditional tool described here is ifconfig. The other options serve different tasks: route deals with routing tables, netstat reports active connections, and ip is the current, more capable utility but not the conventional one being referenced.
