This is open source software, you are free to download the source and compile it yourself (because I'm that nice), however please don't =( I've released the source code so other developers may take and learn from it.
This subnetting calculator is highly configurable, simply input an IP address, and any other field then hit calculate to fill out the information. Supports both CIDR, and Classless subnetting.
The LITE version of the subnetting calculator contains advertisements, and will receive no more extended functionality beyond bug-fixes.
Please submit any feature requests, or bug reports :)
*Fixed a bug where users on a Galaxy S2 could not use dots or spaces by filling out the calculator with default values. (Theres a bug report system on launchpad.net guys, feel free to use it, or email me, it normally takes 2+ seconds to fix issues like these)
*Fixed a bug where application would crash if IP was entered incorrectly
*Added the ability to use spaces as separators instead of periods for the IP address and Subnet mask.
