Start to use IPV6 Networks are here today

IP Address:
Ip address just like a phone number or address used to communicate with another phone or address.
IP stands for Internet Protocol it’s provided to your computer so it can communicate to internet service and other device.
IPv4 and IPv6:
IPv4 is the current version of the Internet Protocol. This system assigns a series of four numbers (each ranging from 0 to 255) to each device. IPv4 only allows for about 4 billion addresses and the Internet needs more room than that.
IPv6 is the new version of the Internet Protocol and expands the number of available addresses to a virtually limitless amount–340 trillion addresses.
Structure of IPv4 and IPV6 (for IPv4) and 2001:db8::1234:ace:6006:1e (for IPv6).
IPv6 launched on june 6 2012
Reason to go for IPv6:
Due to usage of large number of device ipv4 address has not been enough to give the address to all device, so now they need some new format could support large environment system i.e. IPV6
Clearly the internet need to more ip address, so the current IPV4 is totally exhausted.
Many enterprises start to use ipv6 environment .In IPV6 have more features than IPV4
Now Google start to monitoring the world wide IPV6 usage on internet, day by day they update the statistic on internet .Refer the links to see the percentage

Transitions to IPv6 networks, for many enterprises, seem years away. With just 0.51 percent of end users accessing the Internet via IPv6, the traffic is currently low. France has the greatest adoption (4.5 percent), followed by Japan (1.54 percent). And even though IPv4 addresses have been exhausted, But in india they don’t start to use IPv6 environment, but in future it will occupy by more. But it take some times.

Some manufacture company produce the product with IPV6 Environment support, Here is a summary of IPv6 adoption by vendors:

Smartphones and Tablets
Apple iOS (Apple iPhone, iPad) – IPv6 native support with version 4, released June 2010.
Android (Samsung, HTC, Motorola, LG, etc.) – IPv6 support began with version 2.3.4, released in 2011
PCs and Macs
Microsoft Windows – began with XP dual stack in 2001, along with Server 2000 SP1.
Developer code began as early as 1998 with MSRIPv6. Current version Windows Server
2008 and Windows 7 have full native IPv6.
Apple MAC OS X – Mac OS X has shipped support for IPv6 since Mac OS X v10.1, and
enabled it by default since Mac OS X v10.3. Latest version is 10.7.3 released Feb 2012.
Network and Security Infrastructure
Network Switches and Routers – Cisco, Juniper, HP, and Huawei have also supported
IPv6 in their operating systems. Features supported by vendors have changed from year
to year.
Firewalls – Similarly, CheckPoint, Juniper Netscreen, and Cisco Pix have supported IPv6
for years. The key question here is feature parity.
WAN Optimization – Again, feature parity with IPv6 is key. Many vendors claim IPv6
capability, but that claim only applies to a subset of their available features. Blue Coat
is the only WAN optimization vendor that provides all acceleration services over IPv6;
Riverbed and Cisco do not.

Let us see  what features hold IPv6  environment growth..
