There is a lot of information available on the internet that can help you achieve what you
want. In this document, you may be directed to various RFC documents for further
information. An RFC is a Request For Comment (RFC) published by the Internet Engineer-
ing Task Force (IETF), an open organization that defines the architecture and operation
of the Internet. The RFC documents outline and define the standard protocols and
procedures for the Internet. The documents are listed on the World Wide Web at
www.ietf.org and are mirrored and indexed at many other sites worldwide.

For more information about address assignment, refer to the IETF documents RFC 1597,
Address Allocation for Private Internets, and RFC 1466, Guidelines for Management of IP
Address Space.

For more information about IP address translation, refer to RFC 1631, The IP Network
Address Translator (NAT).
