IPv4 against IPv6
IPv4 and IPv6, simply, are versions of IP addresses. IP stands for Internet Protocol; an IP address is a numerical label given to each and every device that can communicate in a computer network that uses IP.
There are no longer any internet addresses available via IPv4 technology. Its successor is IPv6, a system that will offer both simplicity to address assignments and network security features, as well as significantly more addresses. IPv4 uses 32-bit numbers, whereas IPv6 uses 128 bits for the address, allowing a far greater range of numbers, thus available addresses. The internet is expanding and there must be available addresses for users of the internet to use.
To be able to make a comparison, one must first understand what the two types of IP versions are, and what they are able to do.
IPv4
IPv4, Internet Protocol version 4, is the technology used to connect devices to the web. It has been in use since 1978. The 32-bit address technically allows 2^32 possible unique addresses, with some of those addresses being reserved for numerous reasons. Each time a device connects to the internet, it is assigned an IP address. An explosive growth of the commercial internet, and the increaser of IP-enabled devices, has finally exhausted the address space.
IPv6
IPv6, Internet Protocol version 6, functions similarly to its predecessor, however, it will use 128-bits addresses (2^128). As the internet has expanded far quicker than what was ever imaginable, it is important to make it future(ish) proof. Although 2^128 is a far bigger number than 2^32, with more and more devices able to connect to the internet, and the fact no one is entirely sure what might be lying around the corner in web development technologies, it is...

Switches – 2960-24TT Cisco Switch. They are managed switches.
Server – Dedicated computer that is responsible for running a business’s network.
Printer and other peripherals – in order to have a full functioning and usable network.
Cables
There are many types of cables a business could use for its network. Different cables have their own benefits and drawbacks. The design will include:
Category 5 Twisted Pair Network Cable – 100 Mbps with an Ethernet connection of eight twisted wires. Provides Internet connection, as well as voice support and video connections. It is fast, reliable and affordable. As shown in the designs, this Ethernet cable will be used within the training centres to connect devices up.
Serial Communication Link (RS232) – These connect the routers together
IPv4 is the original internet addressing system. It is a protocol which was used on packet-switched networks. Delivery model is how it operates at its best without a guaranteed avoidance of duplicate in delivery or assurance of proper sequencing. Some aspects include data integrity which is mostly addressed by TCP. IPV4 uses binary notation to sort at time IP address that consist of 32 bits. It is a practice to convert the 32 bits of an IPv4 address into four 8 bit known as octets. With each octet converted to a decimal number (base 10) from (0–255) and parted by a period developed a format called dotted decimal notation. IPv4 has a category of address class types: Class A, B, C, D and E. The class A addresses are used for big networks and always start with zero bits. Each Class A address network can hold up as many as 16,777,216 hosts.
What does IP stand for and what is it used for? Internet Protocol, and it's a set of rules governing the format of data sent over the Internet or other
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.
Like a lot inventions in the past two centuries, modern fibre optic cable was created for military uses. The manager for Copper Cable and Wire at the US Army Signal Corps was getting more displeased with the amount of signal loss that was due to copper cable.
The internet has taken the world so far in its short commercial life; the future of the internet provides limitless possibilities of a much different future. The internet was created to test new networking technologies developed to eventually aid the military. The Arpanet, advanced research projects agency network, became operational in 1968 after it was conceived by Leanard Roberts (Watrall, T101, 2/2). Ever since the Arpanet began in 1968, it has grown exponentially in the number of connected users. Traffic and host population became too big for the network to maintain, due to the killer application known as email created in 1972.
TCP/IP addresses are made up of 4 sets of numbers called "Octets." Each octet is an 8 bit binary string. The largest possible value that can be created with 8 characters in binary is 255.
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.
The new communications system will be installed using the existing cabling. The connection that will be used to tie the buildings together will use fiber as a transmission medium. Each of the four buildings is tied together using previously installed multi-mode fiber optic cable. Prior to the installation of this system, this fiber was referred to as “Dark Fiber”, meaning it was not used and therefore no light was being transmitted through it. During the construction of 2 of the 4 building, Structured Cabling was installed to facilitate future communication and data requirements.
Network Address Translation (NAT) is a standard used to allow multiple PCs on a private network to share a single, globally routable IPv4 address. NAT enables a user to have a large set of addresses internally and usually one address externally. The main reason NAT is often deployed is because IPv4 addresses are getting scarce. NAT is an immediate, but temporary, solution to the IPv4 address exhaustion problem that will eventually be rendered unnecessary with the deployment of the IPv6. The Internet Engineering Task Force has been aware of the impending depletion of the current address space for almost a decade.
Computers that reside in this type of network will need to be setup appropriately to avoid issues and receive information from the latest source. And in order to guarantee business progression and future development, companies will need to cautiously develop some sort of plan for their company networks. This is just one option of many solutions for transitioning from IPv4 to IPv6, but can also be costly. Once the distinctions of the two are understood, it is important to understand the advantages that the Network Address Translation has to offer. NAT is able to link a great number of hosts to the worldwide Internet by utilizing one public IP address.

Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
IP address is you Internet identity when you are connected to the web. It is synonymous to a postal address.
Probablemente se habrá encontrado más de una vez con el término "intranet". Aunque una intranet comparte con Internet una gran cantidad de características, al menos en una de ellas, es básicamente diferente. De la misma manera que Internet está teniendo un efecto profundo en la manera en que nos comunicamos, la intranet promete transformar el mundo corporativo. Compañías tan variadas como Ford, Silicon Graphics y Tyson Foods han implementado todas ellas esta tecnología, mejorando la productividad al tiempo que reducen costes.
