A company uses the address block of 128.107.0.0/16. What subnet mask provides maximum equal size subnets?

To determine which subnet mask provides the maximum number of equal-size subnets for the address block 128.107.0.0/16, it’s essential to consider how subnetting works and the requirements for equal-size subnets. The address block 128.107.0.0/16 has a default subnet mask of 255.255.0.0, which allows for a large number of host addresses but does not create subnets. To divide this block into smaller, equal-sized subnets, you need to choose a subnet mask that increases the number of subnet bits while decreasing the number of host bits. When applying the subnet mask of 255.255.255.128, which corresponds to a /25 prefix, you effectively borrow 9 bits from the host portion of the address. This results in a maximum number of subnets calculated as 2^9, which equals 512 subnets. Each subnet will have 126 usable host addresses because the formula for usable hosts is 2^(number of host bits) - 2 (to account for the network and broadcast addresses). The other possible subnet masks do not yield as many equal-size subnets: - 255.255.255.0 (/24) would
