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.
While Star topologies may have many The mesh topology provides multiple routes between devices. Not only does this provide alternates for file transmission should there be a failure anywhere along the network, but it makes it easy for additional devices to be connected and will not slow down network traffic. Since networks built using mesh topology can be large one of the main disadvantages is the difficulty involved with installation, configuration as well as the on-going maintenance involved. The expense of cabling is also a disadvantage of mesh topologies as they can take more cabling and more devices than other topologies. (Networking
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
Fig 3. IP packet fields. 8 2 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).
Since its advent the Internet has been making its way into very farfetched corners of the world, allowing people to virtually reduce distances. Now the Internet was based on a notion called IP (Internet Protocol), Internet Protocol Version 4 (IPv4) to be exact. Now as the number of computer connected
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
NAT also known as Network Address Translation is a method that is utilized by network administrators in setting up IP addresses for network transmission. Network Address Translation allows a piece of network equipment such as a router to behave in such a way as a negotiator amidst public and private

Table of Contents Abstract 2 Introduction 3 Description 4 Abstract With the rapidly approaching global shortage of IPv4 addresses, the current version of Internet Protocol is slowly getting into its limitation of address space and its insufficient security features. IPv6 is the next generation of IP addressing. Used on the internet and on many LANs and WANs
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
Network Protocol: IPv4 to IPv6 Transition Method Introduction 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.
