Private Addresses

Private addresses are reserved IPv4 addresses to be used only internally within a company's network. These private addresses are not to be used on the Internet, so they must be mapped to a company's external registered address when the company sends anything to a recipient on the Internet.

IPv4 Private Addresses

Requests For Comments (RFC) 1918, Address Allocation for Private Internets, has set aside the following IPv4 address space for private use:

■ Class C network—192.168.0.0 to 192.168.255.255

KEY POINT

NOTE RFCs are available at http://www.rfc-editor.org/rfcsearch.html.
