Chapter 1
Configuring TCP/IP

THE FOLLOWING 70-741 EXAM OBJECTIVES ARE COVERED IN THIS CHAPTER:

• 
  Configure IPv4 and IPv6 addressing
  • Configure IP address options
  • Configure IPv4 or IPv6 subnetting
  • Configure supernetting
  • Configure interoperability between IPv4 and IPv6
  • Configure ISATAP
  • Configure Teredo

In this chapter, I will discuss the most important protocol used in a Microsoft Windows Server 2016 network: Transmission Control Protocol/Internet Protocol (TCP/IP).

TCP/IP is actually two protocols bundled together: the Transmission Control Protocol (TCP) and the Internet Protocol (IP). TCP/IP is a suite of protocols developed by the US Department of Defense’s Advanced Research Projects Agency in 1969.

This chapter is divided into two main topics: First I’ll talk about TCP/IP version 4, and then I’ll discuss TCP/IP version 6. TCP/IP version 4 is still used in Windows Server 2016, and it was the primary version of TCP/IP in all previous versions of Windows. However, TCP/IP version 6 is the latest release of TCP/IP, and it has been incorporated into Windows Server 2016.

Understanding TCP/IP

I mentioned that TCP/IP is actually two protocols bundled together: TCP and IP. These protocols sit on a four-layer TCP/IP model.

Details of the TCP/IP Model

The four layers of the TCP/IP model are as follows (see Figure 1.1):

Application Layer The Application layer is where the applications that use the protocol stack reside. These applications include File Transfer Protocol (FTP), Trivial File Transfer Protocol (TFTP), Simple Mail Transfer Protocol (SMTP), and Hypertext Transfer Protocol (HTTP).

Transport Layer The Transport layer is where the two Transport layer protocols reside. These are TCP and the User Datagram Protocol (UDP). TCP is a connection-oriented protocol, and delivery is guaranteed. UDP is a connectionless protocol. This means that UDP does its best job to deliver the message, but there is no guarantee.

Internet Layer The Internet layer is where IP resides. IP is a connectionless protocol that relies on the upper layer (Transport layer) for guaranteeing delivery. Address Resolution Protocol (ARP) also resides on this layer. ARP turns an IP address into a Media Access Control (MAC) address. All upper and lower layers travel through the IP protocol.

Link Layer The data link protocols like Ethernet and Token Ring reside in the Link layer. This layer is also referred to as the Network Access layer.

FIGURE 1.1 TCP/IP model

How TCP/IP Layers Communicate

When an application like FTP is called upon, the application moves down the layers and TCP is retrieved. TCP then connects itself to the IP protocol and gets released onto the network through the Link layer (see Figure 1.2). This is a connection-oriented protocol because TCP is the protocol that guarantees delivery.

FIGURE 1.2 TCP/IP process

When an application like TFTP gets called, the application moves down the layers, and UDP is retrieved. UDP then connects itself to the IP protocol and gets released onto the network through the Link layer. This is a connectionless protocol because UDP does not have guaranteed delivery.

Understanding Port Numbers

TCP and UDP rely on port numbers assigned by the Internet Assigned Numbers Authority (IANA) to forward packets to the appropriate application process. Port numbers are 16-bit integers that are part of a message header. They identify the application software process with which the packet should be associated. For example, let’s say that a client has a copy of Internet Explorer and a copy of Mail open at the same time. Both applications are sending TCP requests across the Internet to retrieve web pages and email, respectively. How does the computer know which return packets to forward to Internet Explorer and which packets to forward to Mail...
