Domain Name Server — DNS — is the TCP/IP facility that lets you use names rather than numbers to refer to host computers. Without DNS, you’d buy books from
184.108.40.206 instead of from
www.amazon.com, you’d sell your used furniture at
220.127.116.11 instead of on
www.ebay.com, and you’d search the web at
18.104.22.168 instead of at
Understanding how DNS works and how to set up a DNS server is crucial to setting up and administering a Transmission Control Protocol/Internet Protocol (TCP/IP) network. (For more on that, see Chapter 1 of this minibook.) This chapter introduces you to the basics of DNS, including how the DNS naming system works and how to set up a DNS server.
