Using Rule 1 and 2 reduce the IPv6 addresses to their shortest form.2001:0000:0000:ABCD:FFFF:0000:0000:0001
A
2001::ABCD:FFFF:0:0:1
B
2001::ABCD:FFFF::1
C
2001:0:0:ABCD:FFFF:0:0:1
D
2001:0000:0000:ABCD:FFFF::0001
Explanation: 

Detailed explanation-1: -Any number of address parts consisting of only zeroes may be compressed by using :: but this can only be done once in an IPv6 address to avoid ambiguity. A good example of this is local host, compressing 0000:0000:0000:0000:0000:0000:0000:0001 to ::1 .

Detailed explanation-2: -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.
