Management Information Systems: IP Address

But how does it work? The internet, based on the concept of “packet switching”, involves the travelling of small packets of data over one or more networks (Frenzel, 2013). This can be compared to “electronic postcards”, meaning that “a computer generates a piece of data and flings it into the net, just like the postal system, except 100 million times faster” (Cerf, 2013). This concept allows one computer to speak to many different computers around the network by sending out these “electronic postcards”. However, before these networks can work seamlessly together, they must use a common protocol, or set of rules for transmitting and receiving these packets of data. There are several protocols currently in use, including the OSI Model, the TCP/IP Model, UDP, HTTP, and FDP (Mitchell, 2014), but the most commonly used is Transmission Control Protocol/Internet Protocol (TCP/IP) (Gilmer, 2011). Even as early as 1977, TCP/IP was being used by other networks to link to ARPANET (Kozierok,

IP stands for ‘Internet Protocol’ and is made of numbers and periods. It is the

Paraphrasing (Stallings, 2007) the function of routers is to get the packet to a destination network. The router reads the header created by the Network Layer of the protocol stack on the source computer. The router can be configured to filter by protocol, source

Router is a device for networking that sends packets of data between the networks of a computer. The packet of data is forwarded to routers of the networks that contain the internetwork until the packet is at the destination node. A router can be linked to several data lines from various systems. The router reads the address information in the packet to establish the ultimate destination when the data packet is in any data lines (Liu, 2012).

An Internet Protocol address is a numerical label given to each device participating in a network that uses the Internet Protocol for communication

A Router is a Layer 3 or Network layer device that connects a network to another network. It connects networks with the same protocol such as RIP (Routing Information Protocol) and IP (Internet Protocol).

A router is a network device, typically connected to a variety of LAN and WAN interfaces, that forwards packets based on their destination IP addresses.

The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was

The two authors follow the story from the conception of the idea of "packet switching" in the early 1960s to the creation and development of the Internet. We see how one idea led to another and how the intelligent people around the circumstances influenced the developments.

The TCP/IP protocols are the heart and soul of the Internet, and they describe the fundamental rules that govern all communications in the network. The original address system of the Internet is Internet Protocol version 4 (IPv4). The Internet Engineering Task Force (IETF) developed IPv6 to deal with the long-anticipated problem of IPv4 address exhaustion. However, IPv6 is not foreseen to supplant IPv4 instantaneously.

Perhaps one of the greatest inventions of out time is the Internet. Without a doubt, the net has had a profound effect on almost every aspect of our lives. The formation of the Internet has changed the way we do business, communicate, entertain, retrieve information, and even educate ourselves. Nevertheless, the Internet might have never materialized if it had not been for some innovated thinkers from the Advanced Research Project Agency, who created "ARPANET." In collaboration with several educational and research institutions, the agency created the packet-switching technologies that form the basis of the Internet today.

Over the next 10 years, we will see a change in technology, and the Internet. Things will continue to progress, and fundamental changes will easily be defined. Technologies have revolutionized how people spread and consume information; these changes will redefine who we are as consumers, merchants, and individuals. With the expansion of computers and the Internet connectivity, people are able to share more of their lives with family and friends. Technology has offered the world so many different services, which include emailing, instant messaging, search engines, blogs, and Wikipedia. These services have changed the way we communicate with others, our knowledge, and the way we conduct business. With the increasing usage of the Internet, developers continue to find ways to improve technology and the way we utilize the Internet. Technology has a wide range of different aspects and concepts, which includes protocols. There has to be rules, and objectives in any and everything we do, and protocols governs communications, errors, detections, messages, and speed. There are three technology concepts behind the Internet, and they are packet switching, Transmission Control Protocol/Internet Protocol (TCP/IP) communications

When connecting your internal network to the internet the need route the packets between the two networks happens inside a router. This translation between the two different networks is known as network address translation (NAT). There are advantages when using NAT as well as disadvantages to the end user, network administrators and overall functionality of the network. We also have to understand the differences between IPv4, IPv6, and the need for NAT in each as they are different protocols and will operate differently ("Network Address Translation," 2015).

The Domain Name System or DNS is an international address system developed to ensure that every computer connected to the Internet has its own address. DNS assigns addresses to Internet web servers [10]. However, in the DNS system, that address is actually a set of numbers like 173.194.39.78. This set of numbers is called the computer's Internet Protocol (IP) address.

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.
