Which command helps display the routing table in a TCP/IP network?

The command that displays the routing table in a TCP/IP network is "Netstat -r." When executed, this command provides a comprehensive view of the current routing table, including information about the network destination, gateway, subnet mask, and the interface used for routing. This table is crucial for understanding how data packets are directed through networks, as it details the paths available for data transmission.

In contrast, the other commands serve different purposes. "Tracert" is used to trace the route that data packets take to reach a destination, thereby providing information about each hop along the way but not presenting a routing table. The "IPconfig /all" command displays detailed information about the network configuration of a device, including IP address, subnet mask, and default gateway, but does not show the routing table itself. Lastly, "ARP -a" is used to display the ARP table, which maps IP addresses to MAC addresses, not the routing table. Thus, "Netstat -r" is indeed the most appropriate command for viewing the routing table in a TCP/IP network.
