Simplest answer:
2^9 -2 will give you 510 host.
9 is # of bits
so, it will be 255.255.254.0
Subnet mask go by 128, 192, 224, 240, 248, 252, 254, 255
254 - 252 (pervious subnet mask) = 2
so network is increment of 2 starting from 0
We know that 2*128 -1 = 255 (max allow network) hint: .255
No.of subnets Range of ip
1. 131.112.0.0 to 131.112.1.255
2. 131.112.2.0 to 131.112.3.255
3. 131.112.4.0 to 131.112.5.255
4.
