Which tool is utilized for monitoring and changing network parameters in Linux?

The tool used for monitoring and changing network parameters in Linux is Ifconfig. This command-line utility allows users to view and configure network interface parameters, such as IP addresses and netmasks, enabling effective management of network connections. Ifconfig can display information about all currently active interfaces, and it can also bring interfaces up or down, assign new IP addresses, or modify other network settings.

Other tools mentioned in the choices serve different purposes. For instance, Netstat is useful for monitoring network connections and routing tables but does not allow for changing network configurations. Ping is primarily used to test connectivity between network devices by sending echo request packets, while Traceroute helps to examine the path data takes across a network by listing all the hops between the source and destination. However, neither Ping nor Traceroute provides the capability to change network parameters. Hence, Ifconfig is the right choice in this context.
