Explanation: 

Detailed explanation-1: -For above example 2001:db8:0:b:0:0:0:1A, we have a series of three consecutive fields of hexadecimal zeros as marked 2001:db8:0:b:0:0:0:1A. We can further simplify and shorten the above IPv6 Address as 2001:db8:0:b::1A.

Detailed explanation-2: -An IPv6 (normal) address has the format y:y:y:y:y:y:y:y, where y is called a segment and can be any hexadecimal value between 0 and FFFF. The segments are separated by colons, not periods.

Detailed explanation-3: -After applying rule 2 to 2001:db8:cafe:0:835:0:0:aa0/80, we calculate the outcome as 2001:db8:cafe:0:835::aa0/80.
