Which shortened address is an accurate representation of the IPv6 address 2001:0db8:0000:0000:ab00:0000:0000:0000?

  • 2001:db8:0:0:ab::
  • 2001:db8:0:0:ab00::
  • 2001:db8:0:ab00:0
  • 2001:db8::ab00::

Explanation: There are two rules to help reduce the notation of IPv6 addresses. The first one is to omit any leading 0s (zeros) in any hextet. The second one is that a double colon (::) can replace any single, contiguous string of one or more 16-bit hextets consisting of all zeros, but the double colon (::) can only be used once within an address. If an address has more than one contiguous string of all-0 hextets, the best practice is to use the double colon (::) on the longest string. So, applying the first rule in the IPv6 address we have 2001:db8:0:0:ab00:0:0:0, and applying the second rule results in 2001:db8:0:0:ab00::
