Which Microsoft Windows utility shows a computer's IP addressing and connectivity settings?

The utility that shows a computer's IP addressing and connectivity settings is IPconfig. This command-line tool is specifically designed to provide detailed information about a computer's network configuration, including its IP address, subnet mask, and default gateway. It is extremely useful for diagnosing network issues and understanding how a device is configured to communicate over a network.

The other options serve different purposes in network diagnostics. Ping is used to test the reachability of a host on a network and measure the round-trip time for messages sent to that address. ARP (Address Resolution Protocol) is utilized to map IP addresses to MAC (Media Access Control) addresses, helping to facilitate communication on a local network. Tracert (or traceroute) tracks the path that packets take to a specific destination, providing a way to see the route and potential latency at each hop.

Thus, for obtaining specific IP address information and connectivity settings, IPconfig is the appropriate utility to use.
