Hello

I was wondering if all the networking experts could help me out. I am studying CCNA in my spare time. I run my own business during the day. I do not have a clue about networks and have thrown myself into the deep end. I have come across this sub-netting stuff. I read all the material and finally think I have it cracked. The thing is, I have tested myself out on a few questions but I don’t know if I am right.

So could someone check please?

I will just show my answer not all the working out I did.


1. IP address allocated is 196.80.20.0

a. What class of IP address is this?

(My answer is class C)


b. What mask should be applied to give 18 useable hosts per subnet?

(My answer is 255.255.255.224)


c. What mask should be applied to give 20 subnets?

(My answer is 255.255.255.248)


2. The IP address allocated 150.16.0.0, 255.255.192.0.

Wow many possible subnets and usable subnets are there? How many hosts and useable hosts in each subnet?

(My answer 4 total subnets, 2 usable subnets, 16384 total hosts, 16382 usable hosts)



3. IP address allocated is 198.220.8.0, 225.225.225.240.

a. What is the network address of the third (2) subnet?

(My answer 198.220.8.32)

b. What is the broadcast address of the tenth (9) subnet?

(my answer 198.220.8.159)

c. What is the address of the first useable host in the fourteenth (13) subnet?

( my answer 198.220.8.209)
