Overview/Description Once you have the subnetting basics down and understand how to divide a network into two or more networks you are ready to determine the optimal subnet mask for a given scenario and how to calculate the usable range of IP addresses that can be used in each of those subnets. This course starts by reviewing and working through a detailed subnetting example that has specific requirements. Next the course introduces block sizes which tell you how many addresses are within the network. It also explains how the first subnet address is reserved to refer to the network itself...

Overview/Description The growth of the Internet and the adoption of networking over the past 20 years are pushing the IP version 4 (IPv4) to the limits of its addressing capacity and its ability for continued growth. To sustain the evolution of the Internet and the ability to scale networks for future demands requires a limitless supply of IP addresses and improved mobility. In response, the Internet Engineering Task Force (IETF) developed a next-generation protocol, IP version 6 (IPv6). IPv6 satisfies the increasingly complex requirements of hierarchical addressing that IPv4 does not satisfy...

Overview/Description Understanding the benefits of computer networks and how they function is important in maximizing communication channels among end users. This course describes the concept of computer networking, introduces the components of a computer network, and explains how users benefit from using networks. The host-to-host communication models were created to help define how network processes function, including the various components of networks and the transmission of data. Understanding the structure and purpose of the most commonly used protocol stack TCP/IP is central to...

Overview/Description Understanding the packet delivery process is a fundamental part of understanding networking devices. You must understand host-to-host communications to administer a network. This course provides a step-by-step analysis of host-to-host communications and the packet-delivery process over a routed network. The course also illustrates the role of Layer 2 and Layer 3 addresses in packet delivery, as well as the role of ARP. Routing is the process by which a packet moves from one location to another. In the terms of computer networks, it is the process of determining where to...
