You have a class A network address 10.0.0.0 with 40 subnets, but are required to add 60 new subnets very soon. You would like to still allow for the largest possible number of host IDs per subnet. Which subnet mask should you assign?

First of all, we should know what is subnetting -it is a process in which we decide the subnet mask into parts and for that purpose, we have to convert last bit of network(1's) id in to host(0"s) id.

After converting.
11111111 11111110 00000000 00000000
11111111 11111111 00000000 00000000
After converting.

Can anyone help me to solve this example?
Define the subnet mask to be used in Class-B addressing to support 30 subnet and also find the most possible in each subnet?

In class a number of host are 3. The first host are divided in number of host so total host are 100 in binary form 1100100.
There are 7 bit it implies that 7 bit (1's). So11111111.11111110.00000000.00000000.

Required network = 100.
Available bits are = 32 bits.
Network id for class A = 10(block 1). 0(block 2). 0(block 3). 0(block 4).
So to create 100 subnet, we require 7 bits of block 2 and extra 1 bit we can use for host id.
So subnet mask will be (255-1) = 254!

As we need 100 subnets which is greater than 64 but less than 128 implies portion of IP address identifying no of subnet need at least 7 1's. Therefore subnet mask has at least 15 1's and at most 17 zeros. So max. number of host can be assign to this mask only. So subnet mask will be 255.254.0.0.
