One of my biggest gripes is the kids who brag how they can break into or circumvent security systems at institutions such as schools. Being a former tech/administrator at a school makes me very sensitive to this issue. I must admit a bit of hypocrisy, since as an instructor at a previous institution, I had to do just that to get materials I needed to teach a class. Actually I did have the authority to do it. If these kids want to play hacker why not do it to their own stuff and leave everyone else alone. Maybe if they have to set up their own system, they might have a bit more respect for all the hard work that goes into the internet.
That leads me to the second issue. Government agencies and other Holy institutions are threatening to cut off or hide the internet from the public at their discretion. Will you still be able to operate your network if the internet so allegedly locked down. Technically it will not be locked down, but the internet phone book aka Domain name servers will hide the data needed to convert a URL (i.e. www.google.com = 126.96.36.199) to an ipadress or sort of computer network phone number. The second part of this is if you get your local computer phone numbers from the internet, will your network also go down so to speak if the internet is locked down? Most home routers properly set up will avoid this.
The real story:
You can actually set up your own network independent of the internet and be completely autonomous. Some people might call this a sandbox. Well if the hackers want to play they need to be in a sandbox or intranet. Your network should be able to turn into a sandbox if needed to also. To make a long story short, I did an instructable to help people do just that. You can find it at: http://www.instructables.com/id/Your-personal-intranet-Part-1/
