Understanding TCP/IP Networking: Addressing, Subprotocols, and Applications

This chapter delves into the intricacies of TCP/IP networking, focusing on addressing and essential subprotocols like BOOTP, DHCP, WINS, and DNS. Readers will gain insights into IP addressing, including its structure and the significance of network and host portions. Additional emphasis is placed on practical applications of TCP/IP, such as troubleshooting network issues and utilizing Internet browsers, e-mail, and e-commerce platforms. Learning these fundamentals will provide a well-rounded understanding of modern networking and facilitate effective communication in digital environments.

    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
