Explanation:
Detailed explanation-1: -64-60 = 4, and 24 is 16, so there are 16 /64 subnets in a /60.
Detailed explanation-2: -In order to represent 64 subnets, we need 6 bits(2^6=64). Since Class B has 255.255. 0.0 as default network ID, when we use 6 bits for subnet mask, then we get subnet ID as 255.255. 252.0.
Detailed explanation-3: -Medium customers get a /56 prefix. That gives them 256 /64 subnets.
