What command can be used to both display and set the IP address, netmask, and default router values?

The command that can be used to both display and set the IP address, netmask, and default router values is the "ip" command. This command is part of the iproute2 package, which is a collection of utilities for managing networking in Linux.

Using the "ip" command, you can perform a variety of networking tasks including retrieving the current network configuration details and modifying these settings. For example, you can use commands like ip addr to display network interfaces and their assigned IP addresses, and ip route to view or manipulate the routing table. To set the IP address or netmask, you can use commands like ip addr add [IP address]/[netmask] dev [interface].

The "ifconfig" command, while it has historically been used for similar purposes, is largely considered deprecated in favor of the more powerful and versatile "ip" command. It is primarily used for displaying network interface configurations but has limited capabilities for setting configuration options compared to the "ip" command.

The "route" command is specifically designed to manipulate the IP routing table, such as adding or deleting routes, and does not have the ability to set IP addresses or netmasks directly.

The "netstat" command is
