IPv6 is the next generation of the Internet Protocol (IP) address standard that will supplement and eventually replace IPv4, the protocol many Internet services still use today.
Originally, Internet Protocol (IPv4) was designed to connect every computer in the World, but a computer was something big at that time. With mobile phones and Internet of Things (IoT), the 4,2 billion of Internet addresses are not enough for everyone and every device, and the original IP address scheme, called IPv4, is running out of addresses.
While IPv4 has maximum 4.294.967.296 addresses available theorically, IPv6 supports up to 340.282.366.920.938.463.463.374.607.431.768.211.456 addresses, enabling anything to be connected to Internet, in the Internet Way of Networking model.
Together with our sponsor and provider Rack66, we are currently implementing our website in full IPv6 (address: 2a01:aa00:0:5::1:49) next to our IPv4 address (184.108.40.206).
