Appendixes Installing and Configuring TCPIP You can install TCPIP on your Windows computer without adding any other software or hardware. Windows 98, 2000, and XP come with Microsoft’s TCPIP protocol suite built in; all you need to do is configure it. It’s important to note that you can install TCPIP for two differ- ent purposes — LAN use or dial-up use. For LAN use, install TCPIP on the Network dialog box and bind that protocol to a network interface card, or adapter. Binding assigns the protocol to the device so that they can work together for communications over the network. For Internet or remote access use, install TCPIP through the Dial-Up Networking window. You install the protocol on a specific connection. See Chapter 10 for more information about using TCPIP on the LAN. See Appendix C for information about using TCPIP for remote access. If you want to use TCPIP to connect to the Internet, see Chapter 16 for more information. Using TCPIP with Windows 98 When you install TCPIP on a computer on the LAN, you enable it to communicate with other computers that use the same protocol. You must install TCPIP on each computer on the net- work, use a unique IP address for each computer, and use the same subnet mask for each computer you configure. You do not use this method of installation if you used LinkLocal to activate automatic private IP addressing. You already may have installed a network client and adapter. If not, you can install those at this time. See Chapter 9 for more information. Note Cross- Reference Web Servers and TCPIP Addressing Using private IP addresses doesn’t affect your use of the Internet. You still can attach to the Internet by using your dial-up networking TCPIP. You can add a Web page to your ISP’s Web server, if you want. Your LAN IP addresses are separate from your Internet connection. Adding a Web server to your network, however, might complicate matters a bit. A Web server is a computer you attach to the Web so that you can display your own Web site. Generally, you install a special operating system such as NT Server and a Web server application such as Internet Information Server on the computer. You also should install a proxy server or firewall to keep Internet users from accessing your LAN through the server. Proxy servers and fire- walls keep people from hacking into your LAN; they can also keep your LAN users from access- ing certain Internet sites. To attach your Web server to the Internet, you need an IP address and a domain name. That IP address applies only to your Web server, not to the rest of your network. You can keep your orig- inal IP addresses for your LAN, as long as you use a firewall or proxy server to separate them from the Web server and none of the computers using a private IP address try to get onto the Internet.
