Q1) Explain the concept of subnetting and the concept of subnet masks. Why do we use subnetting? How do we know which bits are used to identify the network?

Q2) Present and discuss the results in Lab report. Why is it possible to make two subnets when a class C address and subnet mask of 255.255.255.128 was used? What happens when 255.255.255.255 is used as a subnet mask? What is the difference in the results when class B address is used? Press the CIDR Calculator tab. Enter address 132.168.123.144. Choose CIDR subnet mask to be 15 bits long. Generate 4, 32, 128 and 2048 subnets. Note the number of subnet bits needed for each case. Note the Host range and the Subnet Size for each case.

Q3) Explain the obtained results.

Q4) Consider a router that interconnects three subnets: subnet 1, subnet 2, and subnet 3. Suppose all of the interfaces in each of these three subnets are required to have a prefix 223.1.17/24. Also suppose that subnet 1 is required to support up to 125 interfaces, and subnets 2 and 3 are each required to support up to 60 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints. You can use Advanced Subnet Calculator to solve this problem.
