Background / Preparation

Every computer connected to the Internet has a unique identifier, called an IP address.  IP addresses are displayed as four numbers, known as octets, separated by periods (example: 192.168.1.4).  The ipconfig /all command displays your computer’s IP address and information about the network. The following resources

are required:

·      A workstation that is attached to the local network and that has it’s IP address already configured
