The Internet operates by transmitting data
in small independent packets across networks based on an international
communications protocol called the Internet Protocol. IPv6 is the latest version of the Internet Protocol.
These days, in addition to every computer, nearly every cellular telephone and gaming console is connected to the Internet and this is without mention of the infrastructure hardware that required to make these devices work. As a result of this rapid growth the Number Resource Organization states that less than ten percent of them remained in the Internet Assigned Numbers Authority (IANA) free pool as of the beginning of 2010. Through the use of tools like Network Address Translation (NAT), users have extended the life of IPv4, because NAT allows multiple devices to speak to the Internet through a single IP address, while the router in that particular household or business keeps track of which device(s) are receiving and sending information.
IPv6 (the newer Internet Protocol) holds 340,282,366,920,938,463,463,374,607,431,768,211,456 IP addresses. This exponentially larger pool of IP addresses is the key to the future growth of the Internet, and companies that use and distribute IP addresses will need to adapt their networks and systems to use IPv6. Without IPv6, the Internet's expansion and innovation could be limited, and the underlying infrastructure will become increasingly complex to manage. The additional costs from delaying deployment will make life harder for Internet operators, application developers, and end users everywhere.
Here is an example of an IPv6 address: 3ffe:1900:4545:3:200:f8ff:fe21:67cf
Eventually, all IPv4 addresses will be phased out. This is not anticipated to happen for a long time, not before the middle of 2012.

What was used before IPv6?
The first widely used and standardized Internet Protocol was IPv4 (Internet Protocol version 4) and it defined how the Internet and its connected devices operated and communicated with one another. When IPv4 became the Internet standard, the 4.2 billion possible IP addresses were never intended to house a global commercial Internet. In fact, in 1981, there were only a limited number of computers that needed to connect to the Internet (mostly American government and research entities). The pool of IP addresses has been in use for the entire history of the commercial Internet, but recent technological developments have driven the available IP address pool close to depletion. Just imagine that when the Internet was created, web-capable phones were far from being invented.These days, in addition to every computer, nearly every cellular telephone and gaming console is connected to the Internet and this is without mention of the infrastructure hardware that required to make these devices work.

What is an IP Address?
As you can assume, IP stands for Internet Protocol and this is the methodology for communication between devices on the Internet. The IP Address is a number that uniquely identifies a device on a computer network and every device that is connected to the Internet must have a unique address for transport protocols to move information around the Internet. The fact that the same 4.2 billion IP addresses originally devised are almost deplete indicates the need for more.Why use IPv6?
The solution to IP address depletion is simple and that is to develop a more robust numbering system that will allow for far more IP addresses.IPv6 (the newer Internet Protocol) holds 340,282,366,920,938,463,463,374,607,431,768,211,456 IP addresses.

How do I know if my ISP supports IPv6?
IPv6-test.com is a free service that checks your IPv6 and IPv4 connectivity and speed, diagnoses connection problems, and discovers which address(es) you are currently using to browse the Internet. It additionally shows your browser's protocol of choice when both v6 and v4 are available.The other test sites include:
