  • By looking at the addressing structures, you can see that even with a Class C address, there are a large number of hosts per network. Such a structure is an inefficient use of addresses if each end of a routed link requires a different network number. It is unlikely that the smaller office LANs would have that many devices. You can resolve this problem by using a technique known as subnet addressing.

  • Every IP address must be accompanied by a subnet mask. By now you should be able to look at an IP address and tell what class it is. Unfortunately your computer doesn’t think that way. For your computer to determine the network and subnet portion of an IP address it must “AND” the IP address with the subnet mask.When you take a single network such as 192.100.10.0 and divide it into five smaller networks (192.100.10.16, 192.100.10.32, 192.100.10.48, 192.100.10.64, 192.100.10.80) the outside world still sees the network as 192.100.10.

  • Administering Cisco QoS in IP Networks discusses IP Quality of Service (QoS) and how it applies to Enterprise and Service Provider environments. It reviews routing protocols and quality of service mechanisms available today on Cisco network devices (routers, switches, etc.).This guide provides examples and exercises for a hands-on experience to give you the background and necessary details to implement these capabilities in your network today.

  • When you’re subnetting an IP address for a network you have two options: classful and classless. Classful subnetting is the simplest method. It tends to be the most wasteful because it uses more addresses than are necessary. In classful subnetting you use the same subnet mask for each subnet, and all the subnets have the same number of addresses in them. Classless addressing allows you to use different subnet masks and create subnets tailored to the number of users in each group. This technique is referred to as VLSM....

  • Chapter 19 discusses logical or IP addressing. We first discuss the historical classful addressing. We then describe the new classless addressing designed to alleviate some problems inherent in classful addressing. The completely new addressing system, IPv6, which may become prevalent in the near future, is also discussed.

  • We have all heard the saying "It’s what’s inside that counts" at some point in our lives. In the world of networking Cisco’s Internetwork Operating Systems (IOS) has taken that saying to heart. The very core of Cisco Systems phenomenal success is the breadth of services provided by the Cisco IOS software. No two networks are exactly alike. There are connectivity requirements that differ between healthcare and manufacturing, entertainment and shipping, finance and telecommunications. Each of which has different security issues.

  • This is the first part of the Semester 2 practical final exam. It will focus on your ability to configure the lab routers to communicate properly. You will work in teams of five to configure all five Cisco routers and attached workstations so that they share an IP addressing / subnet scheme and a common dynamic routing protocol (e.g.: RIP, IGRP etc.). This will enable them to route packets from a network on router LAB-A to a network on router LAB-E. The NVRAM (startup config file) in all five routers will be erased prior to starting the exam. Your team will select a single class...

  • Currently the Internet has only one level of name resolution, DNS, which converts user-level domain names into IP addresses. In this paper we borrow liberally from the literature to argue that there should be three levels of name resolution: from user-level descriptors to service identifiers; from service identifiers to endpoint identifiers; and from endpoint identifiers to IP addresses.
