Internet upgrade from IPv4 to IPv6: A new Era of Internet World

Yes, our internet will be launched with IPv6 soon. IPv6 is the next Internet Protocol version for whole Internet World. Before we give any more information on this lets see some basic of these IPv’s.
What is IPv?
IPv (Internet Protocol version) is a version of the Internet Protocol (IP) intended to succeed IPv4, which is the communications protocol currently used to direct almost all Internet traffic. We are now mangaing our Internet world using IPv4.
IPv6:
World IPv6 Launch on June 6, 2012, marks the start of a coordinated rollout by major websites and Internet service and equipment providers.
Why IPv6?:
The problem is that the current Internet addressing system, IPv4, only has room for about 4 billion addresses which is not nearly enough for the world’s people, let alone the devices that are online today and those that will be in the future: computers, phones, TVs, watches, fridges, cars, and so on.
More than 4 billion devices already share addresses. As IPv4 runs out of free addresses, everyone will need to share. When we start using IPv6, we get about 340,000,000,000,000,000,000,000,000,000,000,000,000! that is read like 340 trillion trillion trillion. That’s a number big enough to give everyone on Earth their own list of billions of IP addresses.
How do I test if I have IPv6 Internet Protocol version on my PC?

Features of IPv6:
1. The main advantage of IPv6 over IPv4 is its larger address space. The length of an IPv6 address is 128 bits, compared to 32 bits in IPv4. The address space therefore has 2128 or approximately 3.4×1038 addresses. By comparison, this amounts to approximately 4.8×1028 addresses for each of the seven billion people alive in 2011.
2. In IPv4 it is very difficult for an organization to get even one globally routable multicast group assignment, and the implementation of inter-domain solutions is very arcane. Unicast address assignments by a local Internet registry for IPv6 have at least a 64-bit routing prefix, yielding the smallest subnet size available in IPv6 (also 64 bits).
3. Unlike mobile IPv4, mobile IPv6 avoids triangular routing and is therefore as efficient as native IPv6. IPv6 routers may also allow entire subnets to move to a new router connection point without renumbering.
4.The IPv6 protocol header has a fixed size (40 octets). Options are implemented as additional extension headers after the IPv6 header, which limits their size only by the size of an entire packet. The extension header mechanism makes the protocol extensible in that it allows future services for quality of service, security, mobility, and others to be added without redesign of the basic protocol.
5.IPv4 limits packets to 65535 (216−1) octets of payload. An IPv6 node can optionally handle packets over this limit, referred to as jumbograms, which can be as large as 4294967295 (232−1) octets. The use of jumbograms may improve performance over high-MTU links. The use of jumbograms is indicated by the Jumbo Payload Option header.
6. Like IPv4, IPv6 supports globally unique static IP addresses, which can be used to track a single device’s Internet activity. Most devices are used by a single user, so a device’s activity is often assumed to be equivalent to a user’s activity. This is a cause for concern to anyone who has political, social, or economic reasons for keeping their Internet activity secret.
