IPv6 stands for Internet Protocol version 6. It is the second version of the Internet Protocol to be used generally across the virtual world. The first version was IPv4. IPv5 was a protocol of a different sort, intended to support video and audio rather than all-purpose addressing. IPv6 is also known as IPng, which stands for IP Next Generation.
One of the main upgrades in IPv6 is in the number of addresses available for networked devices. For example, each mobile phone or other kind of electronic device can have its own IPv6 address. IPv6 allows 3.4x10^38 addresses. This is mainly due to the number of bits in each protocol. IPv4 addresses have 32 bits in them and so allow a maximum of four billion addresses. IPv6 addresses have 128 bits.
However, IPv4 is still the protocol of choice for most of the Internet. The transition will be a steady one, and IPv6 is the future of Internet addressing, mainly because industry experts believe that they are close to running out of available addresses altogether.
The American Registry for Internet Numbers (ARIN) has become the latest major Internet organization to warn that IPv4 addresses will run out by 2010. ARIN has now begun issuing letters to ISPs owning blocks of IPv4 addresses, which encourages them to adopt IPv6. The group will also begin making it more difficult to gain new IPv4 addresses via a tougher vetting process.
