You are configuring the IPv6 network infrastructure for a branch office.
The corporate network administrator allocates the 2001:DB8:0:C000::/58 address space for use in the branch
office.
You need to identify the maximum number of IPv6 subnets you can create.
How many IPv6 subnets should you identify?
A.
32
B.
64
C.
128
D.
1024
Explanation:
IPv6 has 128-bit (16-byte) source and destination IP addresses. Although 128 bits can express over 3.4×1038
possible combinations, the large address space of IPv6 has been designed for multiple levels of subnetting and
address allocation from the Internet backbone to the individual subnets within an organization.
