Sub=2x
=2x2x2x2
=16
128.64.32.16.8.4.2.1
0 . 0. 0. 0.1.1.1.1
subnet mask 11111111.11111111.11111111.11110000.
192.168.1.0
192.168.1.16
192.168.1.32
upto 192.168.1.240 as we cant use 192.168.1.256
so the subnet mask is 255.255.255.240

For Class C Address, there are 8 host/subnet bits :-
255.255.255.0
We want 10 subnets :-
2*2*2=8 (less than 10.)
2*2*2*2=16 (fullfill the requirement of 10.)
We see that here 4 bits are required for 10 subnets.
128 192 224 240 248 252 254 255
1 1 1 1 0 0 0 0
So the mask is 255.255.255.240

Hi,
Class C range from 192 to 228 .So,the Subnet mask will
range from 255.255.255.192 to 255.255.255.202 which comes
under class C range of ip address.
