IPv6 addresses are 128-bit long and are represented in hexadecimal format with colons separating each group of four hexadecimal digits. The IPv6 address 2001:0000:0000:0000:0134:fc0e:cc8b:458a is a full representation of the address with leading zeros. However, it can be represented in different ways, but the actual address value remains the same.
Here are the explanations for each valid equivalent IPv6 address:
A. 2001:134:fc0e:cc8b:458a This address is a compressed form of the original address. The leading zeros of each group of four digits are removed, and the address is represented using the fewest number of digits possible. The resulting address is the same as the original address because the zeros in the original address do not change the value.
B. 2001:0:0:0:0134:fc0e:cc8b:458a This address is the same as the original address with leading zeros added to each group of four digits to make them four digits long. This representation is called an uncompressed form of the address, and it is rarely used because it is longer than other forms.
C. 2001:0:0:0134:fc0e:cc8b:458a This address is similar to B but with fewer leading zeros. The groups of four digits are only padded with one leading zero to make them four digits long. This form of representation is also called compressed form.
D. 2001::134:fc0e:cc8b:458a This address is a shorthand representation of the address. The double colon (::) replaces the consecutive groups of zeros in the original address. The double colon can only be used once in an address representation. In this case, it replaces the four groups of zeros between 2001 and 0134.
E. 2001:0::0:134:fc0e:cc8b:458a This address is another shorthand representation of the address. It uses a single zero in place of the four groups of zeros between 2001 and 0134. The double colon is then used to represent the remaining groups of zeros between 0 and 134.
In summary, options A, D, and E are valid equivalents of the IPv6 address 2001:0000:0000:0000:0134:fc0e:cc8b:458a.
