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 176.32.103.205
instead of from www.amazon.com
, you’d sell your used furniture at 66.135.216.190
instead of on www.ebay.com
, and you’d search the web at 173.194.43.64
instead of at www.google.com
.
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.
