The traffic inside can use the large set; the traffic（ ）, the small set. To separate the addresses used inside the home or business and the ones used for the Internet, the Internet authorities have reserved three sets of addresses as （ ） addresses. Any organization can use an address out of this set withoutpermission from the Internet authorities. Everyone knows that these reserved addresses are for private networks.They are （ ） inside the organization, but they are not unique globally.
