Network overlapping check

Your SubnetInfo depenencies are nowhere to be found in this branch. This is basically not useable.

It is obvious you are a smartass; but that only works if you are smart in other, non-ass areas, as well. Your code sample has no imports and neither is there any mention of a Maven or Gradle configuration. Maybe you should go to Google and find out what basic documentation is?

Why Maven or Gradle and not Ant or plain javac?
This is not an OSS project. Just a code snippet without any context that I added here for further reference. There is no intent in making this usable to the rest of the world, thus it has no comments, env, context or anything else.
And it will remain like this.

Thanks for your unsolicited, useless, non-constructive comment! Hope you're not having a too much hard time trying to build this.

@nacx Thanks, this was helpful.
