IPv6 is the successor to the IPv4 system. It was designed to allow for more IP addresses than IPv4, to account for the exhaustion of IP addresses as the internet continues to grow. As a result, IPv6 has more possible unique addresses than IPv4, far more - 7.92x10^{28} times the total number of IPv4 addresses, in fact. IPv6 accomplishes this feat by being composed of eight groups of four hexadecimal digits ranging as high as 65535 in decimal, as opposed to the four groups of digits ranging up to 255 in traditional IPv4. This new format performs the same task as IPv4 addresses, which means that the creation of subnets is still possible and still important to know despite the transition to this new addressing system.
