Function of this App is simple but I believe this App helps your network design.
This app is useful when you split subnet.
You can look for good subnet mask easily because this App shows the below information when you specify mask of the range (for range of IP address) and subnet mask.
- Number of subnets
- Number of host addresses for each
Masks are specified by slider or increase/decrease buttons.
The list of subnets is made when IP address is entered too.
characteristic (Subnet Zero, All-Ones Subnet, Super net) of networks is indicated with icons on list of subnets.
Keypad for IP address helps quick entry.
Both masks are specified when you enter prefix of masks (for instance,/24) on keypad.
