Performing different network operations is inevitable when working with computers. When the computers could not communicate using names; sometimes, it calls for the determination of the system’s dotted-decimal Internet Protocol (IP) address. If network problems are experienced like no network connectivity, the system’s IP address should be examined to verify if it’s correctly configured for network operations.

This implies verifying that Internet Service Providers (ISP’s) or Dynamic Host Control Protocol (DHCP) server assigned a valid IP address or not.

To determine a Windows XP computer’s IP address, a command ipconfig can be used from the command prompt.
