A netmask calculator is basically a script or a program that automatically calculates the netmask numbers for you. Netmask is simply a code of numbers that is used to correctly transfer messages among machines in the same subnet. So, a netmask would work together with the router to determine whether the data goes. For example, if the host�s IP address was 63.243.31.41 and the netmask was 255.255.255.0, the netmask is responsible for telling the machine what numbers in IP address are the subnet and what numbers in the IP address is the machine. In this case, 63.172.202 would be the subnet part while 41 would be the machine part. So, any machine in the 63.172.202 would be part of the (local) subnet and thus, the netmask is exactly what assists in differentiating the IP address.
