Addressing the Network IPv4Network Fundamentals Chapter 6 Objectives Explain the structure IP addressing and demonstrate the ability to convert between 8-bit binary and decimal numbers. Given an IPv4 address, classify by type and describe how it is used in the network Explain how addresses are assigned to networks by ISPs and within networks by administrators Determine the network portion of the host address and explain the role of the subnet mask in dividing networks. Given IPv4 addressing information and design criteria, calculate the appropriate addressing components. Use common testing utilities to verify and test network connectivity and operational status of the IP protocol stack on a host. IP Addressing Structure Describe the dotted decimal structure of a binary IP address and label its parts IP Addressing Structure Describe the general role of 8-bit binary in network addressing and convert 8-bit binary to decimal IP Addressing Structure Practice converting 8-bit binary to decimal IP Addressing Structure Convert decimal to 8-bit binary IP Addressing Structure Practice converting decimal to 8-bit binary Classify and Define IPv4 Addresses Name the three types of addresses in the network and describe the purpose of each type Classify and Define IPv4 Addresses Determine the network, broadcast and host addresses for a given address and prefix combination Classify and Define IPv4 Addresses Name the three types of communication in the Network Layer and describe the characteristics of each type Classify and Define IPv4 Addresses Identify the address ranges reserved for these special purposes in the IPv4 protocol Classify and Define IPv4 Addresses Define public address and private address Classify and Define IPv4 Addresses Describe the purpose of several special addresses Classify and Define IPv4 Addresses Identify the historic method for assigning addresses and the issues associated with the method Assigning Addresses Explain the importance of using a structured process to assign IP addresses to hosts and the implications for choosing private vs. public addresses Assigning Addresses Explain how end user devices can obtain addresses either statically through an administrator or dynamically through DHCP Assigning Addresses Explain which types of addresses should be assigned to devices other than end user devices Assigning Addresses Describe the process for requesting IPv4 public addresses, the role ISPs play in the process, and the role of the regional agencies that manage IP address registries Assigning Addresses Identify different types of ISPs and their roles in providing Internet connectivity Assigning Addresses Identify several changes made to the IP protocol in IPv6 and describe the motivation for migrating from IPv4 to IPv6. Determine the network portion of the host address and the role of the subnet mask Describe how the subnet mask is used to create and specify the network and host portions of an IP address Determine the network portion of the host address and the role of the subnet mask Use the subnet mask and ANDing process to extract the network address from the IP address. Determine the network portion of the host address and the role of the subnet mask Use ANDing logic to determine an outcome. Determine the network portion of the host address and the role of the subnet mask Observe the steps in the ANDing of an IPv4 host address and subnet mask Calculating Addresses Use the subnet mask to divide a network into smaller networks and describe the implications of dividing networks for network planners Calculating Addresses Extract network addresses from host addresses using the subnet mask Calculating Addresses Calculate the number of hosts in a network range given an address and subnet mask Calculating Addresses Given a subnet address and subnet mask, calculate the network address, host addresses and broadcast address Calculating Addresses Given a pool of addresses and masks, assign a host parameter with address, mask and gateway Calculating Addresses Given a diagram of a multi-layered network, address range, number of hosts in each network and the ranges for each network, create a network scheme that assigns addressing ranges to each network Testing the Network Layer Describe the general purpose of the ping command, trace the steps of its operation in a network, and use the ping command to determine if the IP protocol is operational on a local host Testing the Network Layer Use ping to verify that a local host can communicate with a gateway across a local area network Testing the Network Layer Use ping to verify that a local host can communicate via a gateway to a device in remote network Testing the Network Layer Use tracert/traceroute to observe the path between two devices as they communicate and trace the steps of tracert/traceroutes operation Testing the Network Layer Describe the role of ICMP in the TCP/IP suite and its impact on the IP protocol Summary
