Introduction Each day, millions of people around the world get on some sort of device that connects them to the internet where the answers they seek, or trying to seek, are there for the taking. However, since there are probably around a billion devices that connect to the internet, there must be a routing system in place to direct certain information to the devices that request it. Computers and devices have a system in place to direct pieces of information, called packets, to the right place. This system stack is based on four layers with the top layer being the application related, the second layer being transport, the third layer being the network layer, and lastly the physical layer. Each part has a specific process which helps deliver the message to the right device. Specifically, the networking layer will be looked upon as it relates to the address of the device. When putting a stack into an example, one can relate the mail system. The application layer would include the writer and letter being sent. Since the writer is busy, the writer sends someone to put the mail in the mailbox which would be the transport layer. The next layer, the network layer, would be the actual address of the mailbox. Lastly, the physical layer is the process of getting the mail to the destination by stopping at other destinations such as the mail center, airport, and the post office. Each step is important in the process of making this work. However, there is a current problem that is being solved and it relates with the network layer. IP is the most commonly used tool in the network layer but the amount of addresses are running out. Before getting into the details of why that is happening. What exactly is IP? What is IP?

The vast amount of address in IPv6 with its 128 bit address will assure that no replacement will be needed for quite a bit of time as the amount of addresses available equal to that of the number of known stars in space.

IP – The Internet Protocol (IP) - is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet.

IPv6-the next version of IP, already implemented in some of the newest Internet ready devices. IPSEC and congestion control (ECN) functionality are already put into service. Increased address space will decrease the effectiveness of attacks scanning for vulnerable machines.
IPv6 has no fixed compatibility with IPv4. Therefore, from the beginning of the introducing IPv6, several transition techniques have been provided, The IPv6 transition mechanisms are a set of rules applied in hosts and routers, with some effective strategies for addressing and deployment, which are designed to transmit from IPv4 to IPv6 or vice versa with the least interferences. But some of these techniques had not been accepted by internet technical community due to the lack of adequate technical reliabilities. The most successful and widely used transition methods probably are Dual stack, Tunneling and Translation techniques. In the Dual stack technique, both IPv4 and IPv6 can perform concurrently on the same foundation. However, they both can use the same router but not all of the IPV4 policies are supported by IPv6 and in these cases other techniques can be used (Jayasekara et al, 2012). One of these techniques is tunneling, in this method IPv6 packets will be encapsulated in IPv4 packets to transfer across an IPv4 infrastructure. Furthermore, it can be said that several different tunneling technologies have been developed to enable IPv6 connectivity across an IPv4 network and vice versa, generally they have been classified as configured or automatic (Rooney, 2011)In automatic tunnels no pre-configuration is needed and the destination address will be calculated automatically from the IPv6 next-hop address of the IPv6 route, while in configured techniques the end-point hosts will require to configure their IPv4 addresses before the communications through some other techniques such as DHCP, manual configuration...etc. (Loshin, 1999). Another popular technique is translation, in this approach a special method will be provided to...
The highest layer in the OSI model is the application layer. While all other layers provide a general service to the other layers, the application does not provide any general services to the other layers (Melendez & Peterson, 1999). The application layer handles items not addressed in any of the lower levels and also handles details specific to distributed applications. Some examples of distributed applications are the hypertext transfer protocol (HTTP), the domain name system (DNS), and the session initiation protocol (SIP) (Serpanos & Wolf. 2011). The OSI model names the seventh layer as the application layer but does not specifically include any of the above-mentioned examples since the OSI model is abstract. As end users, we utilize the application layer every time we enter an HTTP URL in our internet server.
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 developed to allow disparate devices to work together. The original network has long since been upgraded and expanded and TCP/IP is now a "de facto" standard.
When the Internet was inaugurated to Malaysia by the Malaysian Institute of Microelectronics Systems (MIMOS) in 1987, it is for research and education purposes (Ramadass and Osman, 2012). However, it is later commercialised in 1990 and made available to the public in 1992 as JARING (Joint Advanced Integrated Networking) became the first Internet Service Provider (ISP). In 1996, the Multimedia Super Corridor (MSC) is launched and contributed to the development of information and communication technology (ICT) industry. At the same time, TMNet came into the picture as the second ISP and improved commercial and residential Internet access (APNIC, 2004). The application of modern technologies such as fibre optics like High Speed Broadband (HSBB), wireless transmission like WiMAX and Long Term Evolution (LTE) networks, and satellite services, gave a further boost to internet coverage and speed.

Network first appeared in the 1950s. In the 1950 s, communication researchers recognize the need to allow a regular communication between different computer users and different communication networks. This prompted the dispersed network, queuing theory and research of the packet exchange. In 1960 the ARPA net which is the U.S. Advanced Research Projects Agency (ARPA) according to the sake of the cold war established caused a big technological progress and make it become the de...
TCP/IP is a network model which enables the communication across the Internet. The most fundamental protocol on which the Internet is built. This is made up of the 2 common networking protocols, TCP, for Transmission Control Protocol, and IP, for Internet Protocol. TCP maintains and handles packet flow linking the systems and IP protocol has the ability to handle the routing of packets. However The TCP/IP stack consists of 5 layers first being application layer, the transport layer, then the network layer, the link layer and finally the physical layer. The assignment focuses on the three middle layers and is divided into five parts. Firstly explaining how the TCP and UDP the most vital protocols needed to deliver and communicate.
Due to the demand for the internet to be fast, networks are designed for maximum speed, rather than to be secure or track users (“Interpol” par. 1). The adage of the adage.... ... middle of paper ... ...
Only five years after Barran proposed his version of a computer network, ARPANET went online. Named after its federal sponsor, ARPANET initially linked four high-speed supercomputers and was intended to allow scientists and researchers to share computing facilities by long-distance. By 1971, ARPANET had grown to fifteen nodes, and by 1972, thirty-seven. ARPA’s original standard for communication was known as “Network Control Protocol” or NCP. As time passed, however, NCP grew obsolete and was replaced by a new, higher-level standard known as TCP-IP, which is still in use today.
