commonly used protocol suite on PC LANs. Virtually every OS with networking capabilities supports
TCP/IP, and it is well on its way to displacing all the other competing protocols. Novell NetWare 6
and above, Linux, and Windows XP and newer all use TCP/IP as their native network protocol.
TCP/IP: LAN and Dial-Up Networks
TCP/IP, unlike the other network protocols listed in the previous section, is also a protocol used by
people who have never seen a NIC. People who access the Internet via modems (this is referred to as
dial-up networking in some older Windows versions) use TCP/IP just as those whose web access is
done with their existing LANs. Although the same protocol is used in both cases, the settings vary a
great deal.
Table 17.10 summarizes the differences you're likely to encounter. If you access the Internet with
both modems and a LAN, you must ensure that the TCP/IP properties for modems and LANs are set
correctly. You also might need to adjust your browser settings to indicate which connection type you
are using. Table 17.10 provides general guidelines; your ISP or network administrator can give you
the specific details.
Table 17.10. TCP/IP Properties by Connection Type: Overview
As you can see from Table 17.10 , correct settings for LAN access to the Internet and dial-up
networking (modem) settings are almost always completely different. In general, the best way to get
your dial-up networking connection working correctly is to use your ISP's automatic setup software.
This is usually supplied as part of your ISP's signup software kit. After the setup is working, view the
properties and record them for future troubleshooting use.
IPX and NetBEUI
The IPX protocol suite (often referred to as IPX/SPX ) is the collective term for the proprietary
protocols Novell created for its NetWare OS. It has been replaced in NetWare v 6.0 and above by
TCP/IP.
NetBEUI was formerly used for non-routeable workgroup networking in Windows versions
preceding Windows XP. It has been replaced by TCP/IP in Windows XP and more recent versions.
If you need more information about NetBEUI or IPX, see their respective sections in Chapter 17 of
Upgrading and Repairing PCs, 19 th Edition, available on the disc packaged with this topic.
Other Home Networking Solutions
If you are working at home or in a small office, you have an alternative to hole-drilling, pulling
specialized network cabling, or setting up a wireless network.
