points. The IP address The most basic element of TCP/IP is the IP address. The IP address is a number that ’s unique to each computer. If you know a computer ’s IP address‚ you can communicate with that computer from anywhere in the world. Since TCP/IP is the protocol that the Internet uses and since Internet servers are located all over the world‚ TCP/IP must be routable. Thus‚ when you try to access an IP address‚ your computer must be able to tell whether or not that IP address is located on your

staff members who work in various administration departments (e.g.‚ library‚ maintenance‚ finance) spread over another 10 buildings. There are 4 residence halls that house a total of 2‚000 students. Suppose the university has the 128.100.xxx.xxx address range on the Internet. How would you assign the IP addresses to the various subnets? How would you control the process by which IP addresses are assigned to individual computers? You will have to make some assumptions to answer both questions‚ so

they typically use the application layer address. For example‚ in Chapter 2‚ we discussed application software that used Internet addresses (e.g.‚ www.tsu.edu). This is an application layer address (or a server name). When a user types an Internet address into a Web browser‚ the request is passed to the network layer as part of an application layer packet formatted using the HTTP protocol. The network layer software‚ in turn‚ uses a network layer address. The network layer protocol used on the Internet
