Suppose you are an ISP that owns a / 22 IPv4 address block. Can you accommodate requests from six customers who need addresses for 9, 15, 20, 41, 128, and 260 computers, respectively? If so, how? If not, explain why.
What will be an ideal response?
If an ISP owns /22 address block, then number of addresses available will be 2 32-22 = 2 10 = 1024
We should look at the distribution of these available addresses in a very efficient way. For example, if
we want to assign a block for 260 addresses, 2 8 = 256 is less and 2 9 =512 is a lot (lots of addresses are
wasted). The reader is expected to analyze the situation accordingly and answer the remaining of the
question.
