Which command shows the IP address assigned to a computer running Windows XP or Windows 7?

The command that shows the IP address assigned to a computer running Windows XP or Windows 7 is "Ipconfig." This command is specifically designed to display the current network configuration settings of the operating system, which includes the IP address, subnet mask, and default gateway for each network interface.

When you run "Ipconfig" in the command prompt, it provides a snapshot of the network connectivity for the machine, allowing users to see their assigned IP address along with other pertinent information. This is particularly useful for troubleshooting network connectivity issues or when someone needs to quickly find out the IP address of their device.

In contrast, the other commands serve different purposes. The "Ping" command is used to test the reachability of a host on a network by sending ICMP echo request packets and measuring the response time, but it does not provide IP address configuration details. "Traceroute" (or "tracert" in Windows) is utilized to track the path that packets take from the source to the destination and to identify routing issues, but again, it does not show the local IP address configuration. The "Route" command is used to display and modify the IP routing table, which is not directly related to showing the IP address assigned to the computer.
