Private Addresses

Several addresses have been reserved for private use. Any company can use these addresses in its internal network in production or in experimental networks. The one caveat is that these addresses might not be routed to the Internet. To prevent this, Internet service providers filter out private addresses. Private addresses are described in RFC 1918; with one Class A network,

16 Class B networks, and 256 Class C networks in existence. Table 6-1 lists these private addresses.
