Provides an overview of IP addressing, the current standard IPv4 and the future standard of IPv6. Explains the limitations of IPv4 and the reasoning behind looking for an alternative IP addressing protocol. Addresses the advantages of the new IPv6 addressing technology with improved security, auto-configuration abilities, and improvement in routing. Explores mobile IPv6 features and the concerns with deploying IPv6 now and in the future. Studies Comcast as the first early-adopter of the technology and

without the DNS the internet would be very difficult to access. Today, there are two versions of IP 4 and 6 that use DNS. With the growing number of devices with internet IP address, IPv4 is running out of addresses and will eventually be replaced by IPv6. But until then, it is important to understand the many similarities and contrast between both versions. Domain Name Servers and Internet Protocol The core of how the internet works is the DNS, which was created to simplify the unmanageable computer

fashion. Providing security is not an easy task, since many situations have to be taken into account. The approach IPSec uses to address security is by managing two key concepts: privacy and authentication. In this paper, the MOBILE IPv4 & MOBILE IPv6 with the security considerations are introduced, after that the IPsec is explained, focusing on the IP Authentication Header and the IPsec Encapsulating Security Payload. Then the USE OF IPsec IN MOBILE IP part is treated, finally a performance

necessitating instant router advancements. This method depend on VLAN tagging to permit Layer 2 switches to broadcast or trunk the Ethernet frames encompassing IPv6 payload to one or more IPv6 enabled routers. By advancement of one router to provision IPv6, the switch ports to which its interfaces are linked can be formed as the IPv6 VLAN. Further IPv6 or dual-stacked devices could then be constituted as members of the VLAN, and multiple VLANs could be constituted likewise. An example of this deployment

IPv4 and IPv6 address space and AS numbers. (Princeton.edu) The Internet Assigned Numbers Authority (IANA) is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. APNIC conducts extensive research into the depletion of the free pool of IPv4 addresses to predict timelines for IPv6 transition. There are approximately four billion IPv4 addresses, however not all of these can be used openly on the internet. (computerweekly) IPv6 allows 128

ip IPv4 and IPv6 coexistence (tunneling) protocols Introduction The internet is exponentially growing in size, The number of users of the networks seem to be exploding soon, as nowadays many devices exists that connects through the internet using IPv4 protocol and the amount of those devices has increased in the last few years since not only personal computers and laptops are connected to the network but also devices like smart phones, automobiles with GPS, PDA's, and video game

Abstract--- This document provides an analysis and comparison of IPv4 and IPv6 under various circumstances. It is well understood that IPv6 has been designed to replace IPv4. We have done a feature-by-feature comparison and contrast of IPv6 versus IPv4 and found that IPv6 offers many unique opportunities for increasing a network architectures efficiency and agility. In some sense, there is a competition going on between these protocols, as they are not directly compatible, and network providers

familiar with the IPv6 protocol. Bradley (2012) states the following: Since the beginning of the internet, IPv4 has been synonymous with IP and few people ever stopped to think about which version of the protocol it was. But IPv4 has outlived its usefulness. Its successor, IPv6, after nearly two decades of development is finally ready to replace IPv4 as the backbone of the Internet. (p. 34) With all the new technology and devices now accessing the internet the move to IPv6 will eventually happen
