Coding Challenge: CIDR Networks and IPAddresses

Beeing a software development company doing a lot of work in the cloud computing area we have to deal a lot with IpAddresses. Sadly the java.net.InetAddress does not have all the needed functionality to do calculations based on them. For example we often have to calculate the next IP in a given Network, or check if a IP or Network is in a other Network.

To make the long story short, try to implement the missing parts in the given challenge. As a start you can have a look at:

http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing to get all the glory Details about CIDR.

How does this challenge work ?

I already wrote a very simple test suite, please modify it to your needs, see it as a starting point.

1. Fork the x-cellent challenge GitHub repo.
2. Create a working implementation of the CIDR.java Class, feel free to do architectural changes as you like.
3. Test your program by executing `mvn clean install, all tests should pass.
4. Once you think the job is done, write a simple mail with a link to you fork to: [email protected]

have fun !
