Scenario 9-1: Using Port Numbers

           While you are installing an Internet web server on your company network, the owner of the company tells you that he also wants to build a web server for internal use by the company’s employees. This intranet web server will not contain confidential information, but it should not be accessible from the company’s Internet website. To do this, you create a second site on the web server. The Internet site uses the well-known port number for web servers, which is 80. For the intranet site, you select the port number 283. Assuming that the web server’s IP address on the internal network is 10.54.3.145, what should the users on the company network do to access the intranet website with Microsoft Internet Explorer?

       

Scenario 9-2: Configuring TCP/IP Clients

           Mark is setting up a small Ethernet network in his home by installing network adapters in three computers running Windows 8.1 and connecting them to a switch. Mark only uses one of the computers to access the Internet with a dial-up modem, but he wants to be able to access files and his printer from any one of the three systems. After he installs the network interface adapters, he notes that the default networking components have been installed on all three systems, and he sets about configuring their TCP/IP configuration parameters manually. Of the settings on the Internet Protocol Version 4 (TCP/IPv4) Properties sheet, which must Mark configure to provide the network connectivity he desires, and which can he leave blank?
