To find the best subnet mask that meets the requirement of six usable IP addresses, we need to calculate the number of host bits and the number of host addresses for each option. The number of host bits is the number of 0s in the binary representation of the subnet mask, and the number of host addresses is 2^host bits - 2 (the -2 is to exclude the network address and the broadcast address). The option that has the smallest number of host addresses that is greater than or equal to six is the best choice. Here are the calculations for each option:
