TASK 1: IPv4 Fragmentation: The internet is a collection of many different networks (autonomous systems), each having their own routing and packet processing capabilities. IPv4 is a protocol that allows these different autonomous systems to communicate and provide a mechanism to fragment and reassemble packets if needed. When we connect networks together they might have different maximum packet sizes that can go through the network. Different networks have different maximum packet sizes often known

Since we are running out of IPv4 addresses, in the future certain websites will only maintain IPv6 and the Internet becomes a dual IPv4/IPv6 network. This means that in order for a user to connect with your customers, co workers, users and to guarantee that your website remains easy to get to all Internet users, in particular in rising markets; you need to make sure you also have IPv6. And that your network and IT personnel are aware and prepared for the changeover. Time is running out. There

ratio of its traffic volume is increasing day by day.” (p.727) The IPv4 address pool officially ran out January 31, 2011. While no one can provide an exact date for when the world will have officially exhausted its IPv4 addresses, it is inevitable, and it is close. (ip4depletion) With the world now migrating from IPv4 to IPv6, now is the best time to begin migrating Sample Company to IPv6. Understanding the differences between IPv4 and IPv6 is important as well as the hardware/software requirements

for IPv6 Networks Abstract: IPv6 is designed as a next generation internet protocol. It is considered to replace current in use IPv4 protocol gradually in coming years. IPv6 provides many capabilities and futures over IPv4. Security is a key future supported by IPv6, and is mandatory option in IPv6 networks. Security is not mature in IPv6 as compare to IPv4. With the innovation of new capabilities and application, additional security measure are required for next generation operational network

depleting address space provided by IPv4. Global Internet Assigned Numbers Authority (IANA) gave out the last block of IPv4 addresses in February 2011, making the need to move to IPv6 urgent. Today the question “why to implement IPv6?” has been reframed to “how to implement IPv6?” (Vaughan-Nichols, 2012). With more and more organizations adopting IPv6 for their network, it has now been realized that IPv6 is not just a solution to the limited address space provided by IPv4 but also a path to innovations

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

IPv6 is the successor of IPv4. 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

approximately every 12 months. The current version (IPv4) of Internet Protocol was sufficient for 20 years, but if Internet will continue to grow, pretty soon we will run out of addresses for all connections because IPv4 can handle only 32 bit addresses (which are millions of connections). This is the major drawback of IPv4. The other issues is that IPv4 was not designed to handle real time applications such as video and audio efficiently and IPv4 can create a lot of fragmentation due to the lack of

(Quality of Service) technology has become more relevant and important. IPV6 (Next generation internet protocol) have more features and characteristics then IPV4 such as providing more address space and new fields that can be used to enhance and make the usage of IP Network more frequent even with the sensitive traffic flow. The currently used Ipv4 which has supported the internet for more than 20 years have many problems such as No QOS were implemented, so many other protocols are used to guarantee

Internet Protocol - The Next Generation Internet Protocol, or IP is the addressing system used on the Internet. Due to the rapid expansion of the Internet, the current version, Ipv4, is in need of updating. Internet Protocol version 4 addresses "are 32-bit numbers often expressed as 4 octets in "dotted decimal" notation (for example, 192.168.45.230)." [IANA website]. This system supplies 4,294,967,296 (or 232) addresses. While this number may seem to be plenty, some say the internet is doubling

Internet Protocol version 6 (IPv6) Any information presented about IP version 6 (IPv6) will not be complete without talking about IP version 4 (IPv4), its predecessor. For completeness, a brief introduction of IPv4 will be made. In the networking of computers and devices, the Internet Protocol (IP) plays a very important role. The IP, found at the internet layer of the Department of Defence (DoD) model provides the means for the devices to communicate using logical addresses called IP addresses.

There can be an assortment of devices on a network depending on the size. These devices need an effective method of communication between themselves in order to relay the information to the correct destination. The communication protocols are a set of standards that tell different hardware and software how to transfer data elements between them. When working with the OSI model, the protocols will govern communication between entities on the same reference model layer. Network protocols include mechanisms

version of the IPv4 protocol and both of these protocols are part of TCP/IP suite.TCP/IP is the only protocol for transmission of data over the internet As the internet is not secure place for transmission of secure and confidential information (packets) So to protect this information over the non secure channels(internet ) the IPSec was introduced .IPSec is the worldly know standard for the secure transmission over the internet . IPSec is mandatory for IPv6 and optional for IPv4 deployments .But

being used and why it needs to be replaced. The definition of IPv4 as listed in Techopedia is “fourth revision of the IP and a widely used protocol in data communication over different kinds of networks. IPv4 is a connectionless protocol used in packet-switched layer networks, such as Ethernet. It provides the logical connection between network devices by providing identification for each device. There are many ways to configure IPv4 with all kinds of devices including manual and automatic configurations

interface on a subnet and must be unique within that subnet. For all addresses, the interface ID has to be exactly 64 bits long. This makes the differentiation between network- & host portion easy since the boundary is always the same. On the contrary, in IPv4, the size of the subnet could vary using the Variable Length Subnet Mask (VLSM) technique. The interface ID is created using Modified EUI-64 Format Interface Identifiers algorithm, which takes the 48 bit long MAC address of the Ethernet card and expands

Application Level: An example of a highly important protocol which will be utilized at application level, is HTTP or hypertext transfer protocol. HTTP is the protocol used within web browsers and the entire internet to send and receive specific web page data. HTTP is a controlling protocol, as it determines how documents should be sent, and what the browser should do in response to commands. When accessing a web page, a HTTP command is sent to the pages web server, so that the server may send that

A) What is a network? A network is simply a collection of machines connected in some way that allows them to communicate with each other and share information. To do this the machines have to be connected in some way that allows communication

This paper is about stuff i know little about. I'm eally just riting this so i can get some stuff for myself. I plan on making contributions to this site at a later time. As for now, I will just type this so as to gain access to the site. As you hav noticed I put one space after each end of sentence period, although most common typing books tell you to use two. That is a bunch of hooey. Well I don't know how many words I have but I need my report stat cuz it's due tomorrow. So, with no further ado

OSPF Packet Types: The OSPF protocol using its assigned number 89 runs directly over IP. There are five different packet types used by the protocol. 1) Hello: Hello packet is used to discovery and maintain the neighbours in the area. 2) Database Description: Adjacencies are formed using database description packets. The link state advertisements are summarized by the router and passes the information, through database description packets to the adjacent router. 3) Link State Request: After the exchange
