IPv6 (Internet protocol version 6) is the next upgrade to the Internet protocol IPv4, the more typical form of IP networking that we think of today. (IPv4, for example, uses four values for an IP address, such as 10.12.210.67). IPv6 is designed to provide a much greater number of available addresses for networked devices, enough for every cell phone and mobile electronic device in the world to have its own unique address. The protocol will also provide enhanced security for each device.
