Question 4 (25%) An ISP is granted a block of IPv4 addresses starting with 49.2.0.0/16. The ISP needs to distribute these addresses to three groups of companies as follows: ● ● ● Group A has 32 companies; each needs at most 1000 addresses. Group B has 16 companies; each needs at most 500 addresses. Group C has 8 companies; each needs at most 10 addresses. (a) By using the smallest sub-blocks, design the block of addresses for each sub-block. The three groups must be allocated with consecutive sub-blocks starting with 49.2.0.0. For each Group, list the first and last addresses in slash notation for the first TWO and last TWO companies using the format as shown in the table below. (12 marks) 1st company 2nd company 31st company 32th company 1st addresses Last addresses (b) For each of the groups, find out the number of addresses that can be allocated to nodes in each company AND the total number of usable addresses in each group. (3 marks) (c) Find out how many addresses are still available after these allocations AND the range of available addresses. (3 marks) (d) As a result of company re-organization, the company decides to combine the networks of all group C companies without affecting the current services (i.e. IP addresses allocated to nodes should not change). What is the new network address, broadcast addresses and subnet mask for the combined company? (3 marks) (e) Compare your results in (b) and (d) for Group C. What is your suggestion, in view of the limited supply of IPv4 addresses? (4 marks) Question 4 (25%) An ISP is granted a block of IPv4 addresses starting with 49.2.0.0/16.
