IPCalc

IPv4 Subnet Calculator

This is my first app so please be gentle. :)

IPCalc is a simple IPv4 Subnet Calculator. The app will accept partial addresses and will calculate as you type. You can choose the masklength using CIDR length, dotted-decimal notation or using the slider control. You can save your searches and there is a also a limited history function.

Flick the screen from right to left of the main screen and the app will calculate and list other subnets in the class with the mask selected in the main screen. You can also alter the class length used in the calculation using the drop down so you can do things like "show me all similar /24 subnets of a /22 class".

Flick the screen from left to right of the main screen and the app will do a whois lookup on the address listing who its registered to and current BGP route and AS Number if applicable. Please note data charges may apply to this part of the app.
