Answer: D

Explanation:

An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits (two octets). The groups are separated by colons (:). An example of an IPv6 address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334.

The leading 0’s in a group can be collapsed using ::, but this can only be done once in an IP address.
