The program calculates the following data:
- Network address.
- Dotted quad version of the network mask.
- Hexadecimal version of the network mask.
- Broadcast address.
- The first host address on the network.
- The last host address on the network.
- The number of hosts on the network (excludes network and broadcast addresses).
The netmask may be entered in several different formats:
- CIDR style number of bits
- Dotted quad
- Hexadecimal.

It's very handy for setting up networks (hosts, routers, etc.). The only way it could really be better is to recalculate for changing more than just an address. For example, if a change is made to the number of hosts (and round to the nearest usable value...e.g., can't have 12 hosts, only 13 in a /28), have it recalculate netmask and such. That would be handy for resizing existing networks. As-is, it's still possible with some trial-and-error.
