Suppose you are an ISP with a / 24 IPv4 address block. Explain whether you accommodate a request from a customer who needs addresses for 255 computers. (Hint: consider the special addresses.)

What will be an ideal response?


For /24 address block, number of available addresses will be 2 32-24 = 2 8 = 256. However, a
suffix with all 0s address is reserved for network ID and a suffix with all 1s address is reserved for
broadcast address, so number of addresses that can be assigned to computers/hosts will be 256 -2 =
254.
