Comment:        These addresses are in use by many millions of independently operated networks, which might be as small as a single computer connected to a home gateway, and are automatically configured in hundreds of millions of devices.  They are only intended for use within a private context  and traffic that needs to cross the Internet will need to use a different, unique address.
