Chapter 8: TCPIP and DNS

Overview

TCP/IP, which stands for Transmission Control Protocol/Internet Protocol, is used for communicating between computers and the Internet. Without this protocol, Internet Information Services (IIS) won’t function well.

The Domain Name System (DNS) is a technology that allows resolution of domain names to IP addresses. Every host on the Internet has both a domain name address, such as www.microsoft.com, and an IP address, such as 192.17.3.4.

This chapter delves into how TCP/IP and DNS work and how they relate to IIS. Because no respectable chapter about TCP/IP would be complete without some history, that’s how this chapter starts.
