Professor: Dr. Thomas Watts, PhD, CISSP
Kaplan University Abstract
DNS (Domain Name System) is crucial to the activity on the Internet. DNS provides components to resolve a hostname to an IP (Internet protocol) address. The resolution of a hostname occurs over a hierarchy of domain servers. These domain servers consist of name server knowledge for their explicit domain level. A section of the web address will include the domain level. DNS utilizes IP versions 4 (IPv4) and 6 (IPv6) to help resolve hostnames, and also establishes a connection between each host. The connection between the hosts will allow bits to transmit back and forth. These concepts go into more depth in this research paper.
The keywords are: IPv4, IPv6, DNS, DNS hierarchy Introduction
The Internet is used daily by millions people browsing the Web. Anyone who wants to look at a specific website will type an address in the browser, and a web page will display the appropriate page in the browser. This process is not possible without the utilization of DNS. DNS has a role similar to what a translation service would achieve. What specifically does DNS translate? It translates a name such as www.yahoo.com into an IP address such as 206.190.36.45. This simple function is attained because of three primary characteristics of DNS. First, the mapping of IP addresses are joined to and then referenced against a database; this is commonly known as records. Second, the database is dispensed across numerous domains, which include ISP’s (Internet service providers) (Rampling & Dalan, n.d.). And third, DNS accumulates records besides host mappings; it has knowledge regarding other DNS servers which is used in achieving a name to IP address translation.
It is important to remember that this paper focuses…...

Mountain Bank already has the necessary tools to implement a variety of strategic plans. The key will be making the necessary changes and implementing them in order to gain a substantial and competitive advantage in the marketplace. The banks recent internal studies concluded that their best resources are their tellers. Based on this information I would recommend focusing on this echelon of the workforce strategically.

Competitive business strategy: This strategy would focus on the needs of the customers and how to meet them efficiently and consistently. Every banking business that truly wants to succeed must ask “why will customers bank with us?” This question is the basis for the strategy they must adopt. For Mountain Bank I would recommend a #1 focus on customer service and satisfaction. I am not talking about simple courtesy but the type of incredible service that stands out far from our competitors. Numerous studies have shown that superior service will always beat cost of fees or price. BIGresearch.com, an Ohio-based market intelligence firm, conducted...

... Assignment 1: Ethical Issues In HRM Strategy Trimmier McClellan Dr. Linda Force HRM 530 January 27, 2013 Identify the areas of overlap in the new client organization with others that you have had as clients. If you have limited experience with these types of problems, be sure to research common issues to complete this question. In Human resources (HR), problems can arise when dealing with a company’s productivity, hiring new employees, setting up training, and preventing discrimination. An important task of the human resource department is work with employees so they can be very productive. Productivity most often leads to higher revenue for a company. The HR department usually critically considers the amount of people that work each shift, group tasks, bonuses, and other factors that may keep the morale high. These factors are related to each other, so the challenge is to not affect one factor without largely affecting another. There can be difficulty making changes that do not negatively affect a company’s budget. The HR department is usually responsible for some forms of recruitment. They may attend job fairs send out emails, or post job postings to create interest in the company. Because of globalization, companies have to compete with each other internationally rather than just locally. Companies also have a hard time creating incentives for their employees that help balance work and family. Employees today look for a company that will minimize their personally......

...Unit 1: Exploring DNS Kaplan University IT 530 July 2, 2013 Unit 1: Exploring DNS A domain name system (DNS) serves an important role for those who wish to access other networks, which includes websites. DNS allows for users to be able to be able to access Internet websites through a unique name rather than having to memorize a lengthy set of numbers and periods. In addition, DNS allows for the physical hosting location of a network or website to change transparently without anyone noticing. This is more commonly referred to as when a website changes hosts. Furthermore, DNS serves important functions related to mail by allowing users to connect, send, and receive email messages based off of the DNS of the mail server for a specific network (Karrenberg, 2004). Exploring Hierarchies All domains follow a certain hierarchy top to bottom hierarchy. The order for this hierarchy is: 1. root domain 2. top level 3. second level 4. sub-domain The root domain is a top-level domain that refers to the Internet. This is mostly maintained by ICANN, which is a private organization that maintain this area. ICANN manages the internet protocol addresses as well as the DNS root zones. ICANN also manages the DNS policy on naming abilities for top level domains ("INETDAEMON.com," 2013). The level that most users will first visibly notice when connecting to a domain through DNS is the top level domain. In this domain is the area where users will see .com, .net, and .org,...

...Unit 1 Strategy Unit 1 Strategy Bailey Nelson MT460 Bailey Nelson MT460 A business strategy means the company is set out to achieve its desired objectives. It can simply be described as a long-term business planning. Typically a business strategy will cover a period of about 3-5 years but can sometimes even be longer. Strategic management is a three-tier process involving corporate, business, and functional-level planners, and support personnel. At each progressively lower level, strategic activities were shown to be more specific, narrow, short term, and action oriented, with lower risks but fewer opportunities for dramatic impact. Having a business strategy is very important for a business to run smoothly. As a company, management needs to know what direction they want to go in and then have a plan on how they are going to get there. (http://businesscasestudies.co.uk/business-theory/strategy/business-strategy.html) Long-term objectives are “the results that an organization seeks over a multiyear period. Such objectives typically involve some or all of the following areas: profitability, return on investment, competitive position, technological leadership, productivity, employee relations, public responsibility, and employee development.” This is very important for a business to have so that they know what direction they need to go in when making decisions.
