TransitioningtoIPv6:
In order to supply the demands and to reach the future need n the network there should be a limitless supply of the IP addresses and the an improved mobility. In the IP version 6 (IPv6) which satisfies the complex requirements of the future trend that the hierarchal addressing of the IPv4 is providing. In this the IPv6 uses more different types of addresses which makes the IPv6 more efficient than the IPv4. The following concepts describe its functions and how they are assigned.
In order for the transitioning to the IPv6 from the IPv4 deployments they require a variety of the techniques which are included in the auto-configuration function the transmission mechanism is mostly depend upon the need for the network.
Reasons for using the IPv6:
Approximately 4.3 billion addresses are provided by the Ipv4 address space. And in that address around 3.7 address are actually assignable. And other address which was not assigned are reserved for the some other special other purposes mostly for the private address space, multicasting, loopback testing, and for the testing. On some of industrial figures from the date as of January 1, in 2007 there were about 2.407 billion of the available address in the currently assigned which are either assigned to the end users or the Internet Service Providers (ISPs). And thus makes sense of remaining 1.3 billion addresses for the IPv4 address space.
In the IPv6 address there was a 128- bit binary value, which are displayed as the 32 hexadecimal digits, it also provides the 3.4*1038 IP addresses. And this version of the Ip addressing should provide sufficient and number of networks in order for the future growth requirements. The following tables illustrates the example of difference between the IPv6 and the IPv4 addresses.
And to this type of the technical and the business potentials, there they offers IPv6 virtual of unlimited supply of the IP addresses which are required. This is due to the generous 128 bit addresses space and thus the Ipv6 generates unlimited type of the stock addresses which are more than enough for the allocation of the 4.3 billion type of addresses (which are entire IPv4 internet addresses space) for the each and every human being living in this planet.
The internet and the total IPv6 are fully replaced to the IPv4. And so many people within the internet community are even analysed the issue of the IPv4 address exhaustion and then they publishes their type of reports. According to the exhaustion of the IPv4 the predictions may vary. And some of them predicts that IPv4 address will be exhausted by the 2008 or may be by 2009, and some others define them until 2013 or beyond they will not. However the cannot be disappeared and they simply changes to the IPv6.
Changes are occurring dramatically around the world and the developed countries are already been migrated to the IPv4 to the IPv6.
The IPv6 is more powerful enhancement for the IPv4. There are several Features which are functional and improvements in the IPv6.
