Question

question 14
your organization is issued the ipv6 prefix of 2001:db8:130f::/48 by your service provider. with this prefix, how many bits are available for your organization to create /64 subnetworks if interface id bits are not borrowed?
16
8
80
128

Explanation:

Step1: Identify given prefix length

The given IPv6 prefix is /48.

Step2: Identify target subnet prefix length

The target subnet prefix is /64.

Step3: Calculate available bits

We subtract the given prefix length from the target subnet prefix length. So, $64 - 48=16$.

Answer:

16
