IPv6 Addressing
As already stated, one of the main advantages of IPv6 is the availability of a large address space that is comprised of 128-bits. Every host on a network that implements IPv6 is represented with an IP address of 16 bytes. These addresses are represented in a notation called the hexadecimal colon notation. In this notation, the IP address is divided into eight groups of four bytes. The value in each group is provided in the hexadecimal notation.
An example of an IPv6 address is ABC3:56AC:7845:9078:6757:5645:6787:8900
IPv6 also supports a notation called the abbreviated notation in which leading zeros in groups can be truncated and displayed in a concise form.
For example, if the IP address of a host is ABC3:56AC:7845:0078:6757:5645:0087:ABC4 ...
