    1. 1 Chapter Eleven Networking with TCP/IP and the Internet

    2. 2 Chapter Objectives Discuss additional details of TCP/IP addressing and subprotocols Understand the purpose and uses of BOOTP, DHCP, WINS, DNS, and host files Use TCP/IP protocols for network troubleshooting Understand and use TCP/IP applications such as Internet browsers, e-mail, and e-commerce

    3. 3 Addressing and Name Resolution IP Addressing An IP address is 32 bits in size Every IP address is grouped into four 8-bit octets Octets are separated by decimal points Valid octet numbers range from 0 to 255 and represent a binary address

    4. 4 IP Addressing IP Addressing (cont.) Each address consists of two parts: network and host The network portion of an address indicates whether the device belongs to a Class A, B, C, D, or E network Some octet number are reserved for special functions Dotted decimal notation “Shorthand” convention used to represent IP addresses and make them more easily readable by people

    5. 5 Network Classes
