The easiest way to make subnet calculations. Effortlessly find the number of hosts, network and broadcast addresses for any IP / mask pair.

The resulting values are copiable. You can now make you quick calculations and easily copy a value and paste it somewhere else.

Garbage. Doesn't work.

Can only enter an IP address nothing else works and the entered IP address doesn't even auto calc to the classfull boundary.
