At one time, a wide range of network protocols were in use for PC networks. However, the vast majority of networks today use TCP/IP for their networking protocol because TCP/IP offers so many benefits and is ubiquitous—it’s the standard that everyone seems to rely on today. For example, the Internet won’t work without TCP/IP. This chapter explores how you can manage TCP/IP networks at the command line. Even though the coverage isn’t complete, you’ll find that the command line has a lot to offer when it comes to general management tasks.
