This is a network/subnet/IP address calculator for setting up routers and addresses on IP networks. Real-time updating and copy/paste support is included!

A single slider acts as a selector for the CIDR, the netmask, and to scale the # of hosts needed in your subnet network.

The application is useful for subnetting in tandem with an Android web browser or just for educational purposes. Education is emphasized by real time updating of network, broadcast, netmask, first and last address of the subnet, and the number of usable IPs in several different formats (dotted-decimal, hexadecimal, octal, decimal, binary and decimal). Also there are basic notes.

There is real time updating of output as you change values and move the slider to change the netmask/mask bit. Touching the output will cycle through several different formats. Long presses will enable menus for copying to the clipboard.

IPv4 functionality is finished. IPv6 will follow in an update.

No ads nor special permissions required! Also, this subnet calculator does not suffer from the "there's no dot on my number keyboard" problem.

    Design needs an update bad, the app hasn't been updated since 2012. There are also some annoying bugs. The design prevents the interface from fully being seen on 4.0.4 onward. Reset button and CIDR cannot be seen unless the phone is rotated. IPv6 has been
