Answers.

1.A . The process starts with ICANN (Internet Corporation for Assigned Names and Numbers, http://www.icann.org)which owns the
entire IPv6 block space. Then ICANN assigns large address blocks to RIRs (http://en.wikipedia.org/wiki/Regional_Internet_registry), the RIRs assign smaller block addresses to ISP and ISP assign smaller blocks to companies.



2.D Inside a quartet, any leading 0 can be omitted, and one sequence of 1 or more quartets of all 0s can be replaced with double colons(::). The correct answer replaces the longer 3-quartet sequence of 0s with ::

3.D Global unicast addresses begin with 2000::/3 , meaning that the first 3 bits match the value in hex 2000. Similarily, unique local addresses match FD00::/8, meaning that the first 2 hex digits are F.
