In this Exercise, you will explain IP addres components, contrast classful and classless IP addressing, and explain the function of DNS and DHCP.
Assignment Requirements
Respond to the following scenario with design considerations and recommendations:
You are a IT Administrator for a newly founded company and have been tasked with designing an IP addressing scheme and a plan for allocation and management of IP addresses.
The company will currently have a single, physical location with approximately 145 hosts (computers, printers, etc.) IT plans should accommodate 50% growth within the next two years.
At a minimum, address these specific questions, in addition to any other concerns/considerations. 1. What subnet range/s should be used 2. Should IP addresses be dynamically or statically assigned. 3. Should one or more network/subnets be used? 4. If DHCP is used, should a router,firewall or Windows Server be utilized and why?
Respond in detail. justifying your recommendations. 1-2 pages

I find that the IP address components as being the “core” of the IP addresses. Nothing would work without them. They are like the postal address of a home or office building. Every page you see on the internet has a (postal) IP address consisting of numbers such as 255.25.1.200.0. Each number is a component of that IP address.
When IPv4 was introduced, only the first octet was used for the network number and the remaining three octets were used for the host number. This limited the number of possible networks to a maximum of 254, which was quickly seen to be inadequate. The next revision defined as what is called classful addressing, in which the field for the network number was a different length for differest classes of network, and the remaining bits were used for the host number, so each network class had a different maximum number of nodes.
To overcome these...

Ip Addressing Scenario

...IP Addressing Scenario The first thing that we must take in consideration is the number of hosts (145). For my design, I could use the 192.168.0.0 address space using /21 (192.168.0.1 - 192.168.7.254). My subnet mask on the devices will be 255.255.255.0. I will reserve the first and last 20 or so addresses in each DHCP for statically assigned addresses and network devices / gateway addresses. * 192.168.0.0 /24 for servers-all static * 192.168.1.0 /24 for pc's printers- operational for DHCP 192.681.1.21 - 192.168.1.230 * 192.168.2.0 /24 for wireless  - functional for DHCP 192.168.2.21-192.168.2.230  * 192.168.3.0 /24 for VoIP - working for DHCP 192.168.3.21 - 192.168.3.230 * 192.168.4.0 - 192.168.7.254 for future usage . We should have multiple domain servers and DHCP servers. Firewall always needs to be used even though most computers with windows 7 come with it. Firewall is very important because it block any outside intrusion. That way it can be monitored. All type of security can be implanted to assure that the servers can’t be infiltrate by intruders, like finger print recognition, password expiration…. It will be my responsibility to ensure that all policy regarding the security of each computer and server will meet the criteria. Each IP addresses should be addressed dynamically because it will be easier and it won’t take a lot of time and that way we won’t have to go to each computer and assign them statically. The only that we will have to......

Ip Addressing Scenario

...IP addressing Scenario When you design an IP addressing scheme for a medium to large scale company you need to take into account several questions about the company environment. What type of security is needed? Is the company going to grow past 145 clients? Do all the computers need to talk to one another? Can they be separated out into different departments? What types of content will be shared between users? How many content share servers are there? When setting up an IP scheme you need to take into account the growth of the company. If the company is only going to have 254 devices attached to the network. If the answer is yes then you can proceed with a statically assigned IP scheme. If you answer is no then you need to implement a scheme designed around a DHCP server. Normally when you design a scheme you want to take into account the departments in the company and if they need to be interconnected to the rest of the clients. If there are several departments that need to talk to one another, and a couple of departments that are restricted access clients. These types of question and answers would make an IT professional’s job either simple or more complex. Normally in a IP Scheme you want to choose the IP address that make sense to your network most internal networks sit in the class B or C range. If you choose a network IP of 172.16.0.1 your subnet masks would be at 255.255.0.0 for your choice. If you are going to design a IP scheme around a DHCP Server it might......

Ip Addressing Scenario

...Unit 1 Exercise 1: IP Addressing Scenario To start with, I would use the IP Class C. The subnet range in Class C is 255.255.255.0-255.255.255.255. This would be the best one for this company because there is room to grow. I believe that the IP addresses should be statically assigned. That way, there is not a chance of it getting into any trouble by anyone. One network/subnet would do fine. You have a giant subnet range, plus you have a good size network. If DHCP is used, then yes a router, firewall, and Windows Server should be utilized. You need a firewall, so you don’t have any problems with your employees looking at non-work related websites or websites that haven’t been approved. A router, so that you can have your internet connection protected. You wouldn’t want anyone just hacking into your connection and getting their hands onto any private information that they could get their hands on and ruin your company. A Windows Server would be good as well. You could use the Windows Server so the employees could get their work done, instead of searching the web for non-work related things as well. When you consider this design as a possible outcome, just remember that this plan also involves the growth of the company. The growth of the company is the main concern here. We do not want to stunt the growth of the company. We want the company to grow as much as possible. I believe this design will prove to do that. It will be a great design and will help out very much. We do......

Unit 1 Ip Addressing Scenario

...UNIT 1: IP ADDRESSING SCENARIO First to start off with this scenario you should think about the design. When designing I would use one floor with a single data closet. This will be able to have one hundred and fifty users. There’s a list of equipment and software that’s needed. A core network, networks for your firewall, server network, voice network, wireless network. Also networks for other services you have not yet identified, like security, cameras, fire, door and video. The subnet range would be one-hundred and forty five from one-hundred and forty six. The network number would be one-hundred and forty four. Also the broadcast number will be one-hundred and forty seven. In this case as far as which class it would be is class B. In the case of the how the IP addresses would be assigned I would consider choosing statically. A static IP address is a number that is assigned to a computer by an internet service provider to be its permanent address on the internet. Also an advantage of having statically IP addresses is that they’re easy to use and less expensive. When it comes to maintaining and obtaining they’re easier to have as well. In answering the question about having one or more network/subnets to be used, I would think that you should use multiple network or subnets just in case you want to expand the size of your IP addresses. If you keep everything at its minimum size or space then that’s all you have to work with. If you make sure that you have extra space,......

Case Study 8

...Case Study 8 Based on the January through June 2010 cash budget, what is the maximum monthly loss during the six-month planning period? What is the maximum cumulative borrowing balance? (For purposes of this question, disregard any interest payments on short-term bank loans or interest received from investing surplus funds.) Maximum monthly loss is in June: -$60,750. The maximum cumulative borrowing balance is $99,000 in February. What does the monthly cash budget reveal that indicates it should probably be extended beyond the original six months’ horizon? The major cash shortfall in June and the seasonality inherent in the firm’s business indicate that a full year’s cash budget should be developed. The monthly cash budget assumes that cash flows occur simultaneously. This is not realistic, of course. Assume, more realistically, that cash outflows occur early in the month and cash inflows occur later in the month. What do you think would happen to the current cash budget’s predictive powers? (NOTE: This question should be answered without preparing a spreadsheet; it is a ‘thought’ question.) The monthly cash budget would understate the need for funds, since outflows would occur before inflows. If you identified any issues in #3 above, what do you think would resolve them? HINT: There is a specific answer I am expecting, short and sweet, and it is in the case study narrative. Use a daily cash budget to predict cash flows. The need for cash could...

Change Analysis

...Change Simulation Experience “It is not the strongest of the species that survive, nor the most intelligent, but the ones most responsive to change.” - Charles Darwin Charles Darwin’s groundbreaking theory of evolution was certainly not restricted to species in the wild. Adapting to change in any corporate environment is fundamental to the success of any organization and its employees. Achieving this success depends on a key ingredient – appropriate application of change management that focuses on increasing levels of commitment to change and decreasing levels of resistance. Our group perceived the ‘Global Tech Change Simulation’ to be reflective of real life organizational change as it recreated a business scenario that needed to follow a multi-step process in a timely and sequential manner in order to have a successful outcome. There are challenging barriers to change which include acceptance, adaption and resistance, and each obstacle requires the use of change leadership and best practices to guide an organization through such a transition. Our Approach: What Worked Our group was aware of how essential it was to follow the seven-step Experience Change Model and categorized each tactic according to our analysis of where it belonged within the model – see Appendix A. We started our simulation with balanced participation through stakeholder mapping to ensure that key stakeholders in all departments understood the need for change. Stakeholder mapping allowed us...

The goal of Macy’s, Inc. is to “be a retailer with the ability to see opportunity on the horizon and have a clear path for capitalizing on it” (Company Statements & Slogans, 2008). Macy’s, Inc. sees an opportunity in Kava and needs to make a clear path so that we can capitalize on it. Since Macy’s, Inc has a long standing tradition of believing that giving back is the right thing to do (Macy's Inc, 2011) , we would like to help Kava try to recover from all the disasters they have gone through, and help to overcome the challenges that they are now facing. Macy’s will do this by addressing the issues found in the business scenario, forces involved in the formulation of the problem, and organizational and environmental obstacles impacting key stakeholders.

S2S Business Model

...Constructing Vision with Scenario Planning Terry R. Schumacher Rose-Hulman Institute of Technology, Engineering Management Dept., Terre Haute, IN 47803 USA Abstract Strategic vision is often included as an important component of leadership. Yet there is relatively little guidance offered in the management literature on how to acquire vision. This paper describes practices that facilitate scenario planning so that it becomes a process for creating shared vision. Most of the work on scenarios addresses the mechanics of scenario construction. Those authors adopt a planning perspective and suggest scenario planning can benefit organizations by stimulating creative thinking about the future or improving forecasts. The Scenarios-to-Strategies (S2S) approach is presented, and scenario planning is considered from a communication perspective. Facilitation practices that enhance traditional scenario-building processes are presented which support the social processes of constructing shared vision. These operate on the layer of participants' cognitive processes, to integrate the different participants' views into a unified, shared framework that heightens understanding and commitment. Example scenario planning projects from two industries, electric utilities and software research, are summarized to demonstrate lessons learned that enhance the facilitation of scenarios as a group process. Introduction Scenarios are a commonly used management technique. There is wide variation in the......

Duty to Rescue

...Abstract: The following paper will be written from the point of view of a manager/supervisor and will address various scenarios that may arrise concerning an employee’s behaviour and actions, and how to effectively adress them within the context of employment-at-will doctrine and the liability to the employer. Scenario 1: This scenario deals with an employee who has failed to learn the computer applications that are basic to the job requirements. The scenario assumes that the employee has received a few months of training and support, yet is unable to complete the required tasks in an efficient and effective manner. In analyzing this scenario, the first step I would take in addressing the issue at hand, is to formally counsel the employee in writing, as the information presented does not state if that has been done. The counseling would serve multiple purposes. First, it would serve as a means to formally document the employee’s lack of skills, competency, and abilities, as it relates to the requirement of the job. Secondly, it would clearly delineate the expectations of the position, the criteria under which they will be evaluated, and when the next evaluation will take place. The counseling would also inform the employee that failure to improve may result in administrative action, up to and including termination. Lastly it would require the employee acknowledge via signature that they have been counseled. The reason I have chosen to take the written counseling......

...EMPLOYMENT AT WILL RONALD BLALOCK STRAYER UNIVERSITY PROFESSOR MARK GLANTZ LEGAL 500 April 22, 2012 Describe what steps you would take to address the following scenario involving skills, competence, and abilities? My method for addressing Jennifer’s shortcoming consists of termination based on the employment at will doctrine. As Halbert and Ingulli (2012) report in Law and Ethics in the Business Environment, employment at will gives employers broad discretion to fire employees for a good reason, a bad reason, or no reason at all. This legal doctrine gives organizations the upper hand when releasing an employee. Also, this law allows employees to resign from a position on their own terms. Jennifer is a recent college graduate hired in our accounting firm. She is having issues with our computer applications which she was trained on after hiring. Management has decided to implement new training courses in support of our employee. Over an extended period of time, she is still unable to perform her required duties which reduces productivity and raises production costs. Our organization has taken many preventive measures to reduce and liabilities that may occur from discharging the employee. Her inability to work at a productive level gives our organization a legitimate reason to dismiss her for lack of production. Unfortunely, she continues to perform poorly which places our management team in a position to take appropriate action to resolve poor performance. ......
