Explain what IPv6 is, and why it is being developed?

The Transmission Control Protocol/Internet Protocol (TCP/IP) is a protocol for sending information across sometimes-unreliable networks with the assurance that it will arrive in uncorrupted form. TCP/IP allows efficient and reasonably error-free transmission between different systems and is the standard protocol of the Internet and intranets. It is usually used throughout the Internet. In other words, the Internet does not use much-vaunted Open Systems Interconnect (OSI) seven layers model. It instead uses a …

…each ad hoc upgrade. The new protocol (Ipv6) also lets backbone designers create more expandable hierarchical addressing. Much like the US telephone system, in which three-digit area codes forward long distance calls to local exchanges, IPv6 backbone routers relay packets using a prefix embedded in the destination address, instead of having to revise and store information continually for every network in the world. So, this is basically the reason behind why IPv6 is being developed.
