Detailed explanation-1: -The IPv6 addressing architecture allows you use the two-colon (::) notation to represent contiguous 16-bit fields of zeros. For example, you might abbreviate the IPv6 address in Figure 3–2 by replacing the two contiguous fields of zeros in the interface ID with two colons.
Detailed explanation-2: -Rule 1, called Zero Compression, omits a group of consecutive zeros and replaces them with a double colon (::). This can only be applied once per IPv6 address, otherwise, the shortened representation becomes ambiguous. Rule 2 omits leading zeros in a every group of hexadecimal digits.
Detailed explanation-3: -The leading zeros in each group can be removed. For example, the above address can be represented in a shorter format as 2001:0:130F:0:0:9C0:876A:130B. If an IPv6 address contains one or more consecutive groups of zeros, they can be replaced by a double colon (::).
