Network Technology Case Study

The Network Address Translation overload or PAT is an excellent way to go if a situation where to arise and there was a shortfall of public IP’s. Port Address Translation is just an annex to NAT that allows many devices on a LAN to be drawn to one IP address. The main objective of PAT is to preserve IP addresses, so in a LAN lots of users are

A Star topology is the second type of topology represented. This topology is easy to install as well as being easy to expand by connecting additional nodes or devices. Faults are easily detected and parts are easy to remove. In a Start topology, when devices need to be added or removed, it does not cause disruptions to the network. This type of topology is used for many different applications, ranging from small to large networks. (FCIT, Univ. of Florida)

The organization will reap in high sales and production and possible lower costs in employee wages from less workload. The network system will work at a faster pace and if using the voice-over IP system, communication and management costs can be reduced.

IPV6 addresses can be assigned automatically by the device which should eliminate the need for a DHCP server. It also comes with an option for a built-in encryption which ensures that each package that gets sent has to be decrypted prior to interpretation. Also with the amount of available addresses, NAT is no longer

The Newton Ad Agency will be using a Wide Area Network (WAN) network since its connectivity needs to span over a number of locations. The WAN connection should be able to provide the likeness of a Local Area Network (LAN) connection in regards to performance for the branch offices, support several applications, and have a high performance. The headquarters and two branch offices will use a Virtual Private Network (VPN) connection to the internet and require at least two routers, security gateways, and Ethernet switches at all three locations. All of these devices will be connected with full mesh WAN connections that tie to the Austin headquarters with the utilization of both Internet and private WAN connectivity. This type of connection will allow for Voice over Internet Protocol (VoIP) and video services to be supported and can accommodate both wired and wireless LAN infrastructures. The network will be implemented with the

To outface this problem Network Address Translation (NAT) method is used. This enables devices with private addresses to be connected to a public network address (e.g. Internet). This private address is converted to legal IP address, through NAT routers before traveling 11 “outside”. (See figure 4). Every device that is connected to the network has a unique IP address but this doesn’t mean that is permanent. Because devices connected to the network,

The need for IPv6 is growing by the day. There are good amount of reasons why the migration of IPv6 is not only desirable, but necessary in days to come. Some of the areas were IPv6 benefit from are reduced address space, advanced security features, enhanced quality of service, and stateless auto configuration. (IPv6 and the Future of the Internet).

That being said, there is a multitude of problems while migrating from IPv4 to IPv6. Some might even consider a problem of unprecedented magnitude as the migration can and will affect anything that touches the World Wide Web. It is not just that there are technical aspects of the Internet that will be effected, but there are certain other aspects that need to be regarded

To complete the lofty goal of designing a new network infrastructure the Enterprise Network Engineer must meet several objectives including design of the physical placement of network devices, design of the physical connections between all network devices and design of the segmentation of the network utilizing VLANS. The Enterprise Network Engineer shall utilize several of the previously completed objectives including the network inventory scans and network device configuration audit to assist with the design. The Enterprise Network Engineer will utilize software such as Microsoft Visio to layout design schematics for all proposed hardware per physical location including any previously discussed and approved hardware repurpose recommendations. The Enterprise Network Engineer will include repurposed hardware within the Visio schematics; however, the repurposed hardware may or may not be implemented on the new network

A Global transition to Internet Protocol version 6 is initiated. The government and organizations understand the benefits of this new protocol and are making change plans. The Information technology industry is undergoing a massive transformation. This research paper would outline the migration, transformation, and configuration of Internet Protocol version 6 from Internet Protocol version 4. Currently; we are close to exhausting a lot of our options regarding current Internet Protocol version 4 addresses. The new Internet

There is also the distinction between Public and Private addresses, where public addresses are recognized world-wide, as they are allocated by designated organizations, and that is how they are running out; almost all valid addresses have been allocated. On the other hand, private addresses are used within an organization or a home, however, they require the help of a publicly recognized address to communicate globally, and this is through a process called Network Address Translation (NAT). The allocation of Public IP addresses falls under the authority of IANA (Internet Assigned Numbers Authority), a global body that oversees regional organizations, and these organizations are more directly involved in IP Address allocation.

IPv6 has been around since about 1995, and some companies have been testing it, it is installed on the unit, and enabled by default, but most people have not activated it. Windows 7 and 8 and servers 2003 all are ready for upgrade to the IPv6 network setting. As we know IPv4 only give you 4 billion some user and are completed, the new version IPv6 has an unlimited number of addresses to use, with hope of not running out.

The internet and networks are expanding as many new computers and devices are being used. The configuration of both static and dynamic IP addresses should be simpler.

Since there are so many IP addresses that need to be handled on the Internet, IPv4 and IPv6 need a way to keep track and configure them. This is normally referred to as address resolution. This includes translating network layer addresses into link layer addresses, having automatic assignments of addresses, and routing data to the correct location on a specific network. IPv4 uses a protocol called Address Resolution Protocol, or ARP, in order to translate IP addresses into MAC addresses. A MAC address is the unique number given to the network interface card in each computing device. The reason this needs to be done is because on many intranet networks, the internal communication and delivery of data is based off of the MAC address rather than the IP address. The Dynamic Host Control Protocol, or DHCP, handles the automatic configuration and assignment of IP addresses in IPv4. DHCP is an internal protocol that takes the MAC addresses of the NICs on a network, and automatically assigns IP addresses. It also keeps track of them so that two NICs don’t acquire the same IP address. Without DHCP every IP address would have to be entered manually by the system administrator, which would be incredibly difficult considering how many devices can potentially access a network. IPv6 uses similar methods to perform both of those functions, but there are still important differences that exist to improve the way that IPv6 performs. Instead of ARP, IPv6 uses the Neighbor Discovery Protocol

The network protocol rules include the strategies that have characteristics of a network including the access method that allowed the types of cabling, physical topologies and the data transfer speed. Which in this document the most common research will based on IPv4 and IPv6 addresses and the transition between the two.
