(solution) Designing IP Addressing schemes and configuring IP Addressing is

Designing IP Addressing schemes and configuring IP Addressing is a common activity undertaken by network engineers. Consider an ISP is granted a block of addresses starting with 150.80.0.0/16. The ISP needs to distribute these blocks to 2600 customers as follows:[7 marks]

a. The first group has 200 medium-size businesses; each needs approximately 128 addresses.
b. The second group has 400 small-size businesses; each needs approximately 16 addresses.
c. The third group has 2000 households; each needs 4 addresses.

Design the sub blocks and give the slash notation for each sub block. Find out how many addresses are still available after these allocations.
