Which TCP/IP utility provides detailed information about network configuration on a machine?

The choice identifying the TCP/IP utility that offers detailed information about the network configuration on a machine is indeed correct. This utility, known as ipconfig, is primarily used in Windows operating systems to display all current TCP/IP network configuration values. When executed, ipconfig provides users with important information such as IP address, subnet mask, and default gateway for all active network interfaces.

This tool is particularly useful for troubleshooting network connectivity issues, as it allows administrators to quickly assess whether the network settings are correctly configured. Moreover, it can also be used with various parameters (such as /all) to show additional details like DNS servers and DHCP lease information.

In contrast, nslookup is primarily used for querying DNS records to determine the IP address associated with a domain name, while route is utilized for displaying and managing the routing table on the machine. Ifconfig, on the other hand, is similar to ipconfig but is used in Unix and Linux-based systems to configure network interfaces. Each of these tools serves a different purpose within network management, but ipconfig is specifically designed for providing comprehensive details on network configuration in Windows environments.
