Assume that you are working for a large corporation that wants to use the private IP address range starting at 172.16.0.0 for its internal network. The company management wants to be able to have a minimum of 30 separate sites in Ireland with a subnet for each site, with at least 2000 host IP addresses available per subnet. You are requested to design the network layout. Answer the following questions and fully explain the logic behind each answer: a) What subnet mask will need to be used for the individual subnets in Ireland? 6 MARKS b) What are the valid host addresses and the broadcast addresses for the first and second subnets in Ireland? 4 MARKS c) The company has operations in 15 other European countries and each country has been allocated a /16 address range. These individual /16 address ranges are contiguous and Ireland has been allocated the first of these ranges. What route summary (or supernet) could be used to define a single routing entry for all of the European address ranges? 6 MARKS d) What other private IP ranges could the company use if needed? 4 MARKS e) When is it appropriate to use IP private addressing versus public addressing? 5 MARKS
