Suggested Answer: D Vote an answer

IPv6 Address Notation
IPv6 addresses are denoted by eight groups of hexadecimal quartets separated by colons
in between them.
Following is an example of a valid IPv6 address:
2001:cdba:0000:0000:0000:0000:3257:9652
Any four-digit group of zeroes within an IPv6 address may be reduced to a single zero or
altogether omitted.
Therefore, the following IPv6 addresses are similar and equally valid:
2001:cdba:0000:0000:0000:0000:3257:9652
2001:cdba:0:0:0:0:3257:9652
2001:cdba::3257:9652
The URL for the above address will be of the form:
http://[2001:cdba:0000:0000:0000:0000:3257:9652]/
