Why do you want to do this?

If you want to block access to name information outside your network, it's simpler to block nameservice packets at your firewall or edge routers. One assumes the user base is well in hand if you are even comtemplating blocking their access to .com. so informing them shouldn't be a problem.

If you want "unregistered users" (however that may be defined) to all end up at the same page (sounds like a misguided attempt to use DHCP for security), then you don't need this:
