        Title:      Address Allocation for Private Internets

This RFC describes methods to preserve IP address space by not
allocating globally unique IP addresses to hosts private to an
enterprise while still permitting full network layer connectivity
between all hosts inside an enterprise as well as between all public
hosts of different enterprises.  The authors hope, that using these
methods, significant savings can be made on allocating IP address
space.  For the purposes of this memo, an enterprise is an entity
autonomously operating a network using TCP/IP and in particular
determining the addressing plan and address assignments within that

This memo provides information for the Internet community.  This memo
does not specify an Internet standard of any kind.  Distribution of
this memo is unlimited.

This announcement is sent to the IETF list and the RFC-DIST list.
Requests to be added to or deleted from the IETF distribution list

added to or deleted from the RFC-DIST distribution list should
be sent to RFC-REQUEST at NIC.DDN.MIL.
