It is very important to be able to understand subnet masks with both the dotted decimal as well as the CIDR format. a. Convert the CIDR notation/27 to the dotted decimal format. ____ Convert the dotted decimal subnet mask 255. 255. 224.0 to CIDR notation. _____ Write the correct DEFAULT subnet mask for each of the following IP addresses: a. 177.100.18.4 119.18.45.0 193.100.77.83 You have been assigned one class C network with address 192.168.10.0. Your task is to create 8 networks with a minimum of 30 hosts each. a. What is the default subnet mask? What is the custom subnet mask? Total number of subnets equal ___ Total number of host addresses equal ____ Number of usable hosts addresses _____ From problem 4 above, answer the following. a. What is the 4^th subnet range? What is the subnet address for the 8^th subnet? What are the assignable addresses for the 7^th subnet?

Solution

1.

a) True

b) True, security increases as number of subnets increases

c) False, It is an additional property which is beneficial

d) True

2.)

a) 11111111.11111111.11111111.00000000

b) 11111111.11111111.11100000.00000000

3)

a) 255.255.0.0, Becasue ip address 177.100.18.4 belongs to Class B

b) 255.0.0.0, Becasue ip address 119.18.45.0 belongs to Class A

c) 255.255.255.0 Becasue ip address 193.100.77.83 belongs to Class C
