Sounds good, as per me we should know how to calculate the wilcard mask
manually. But if we are being given the option to use the calculator then
its great as it will save some time, head can concentrate on something else
during that time. Also, we might tend to make some human errors while
calculating in our heads. Thanks for your reply!
