        Title:      The IP Network Address Translator (NAT)

The two most compelling problems facing the IP Internet are IP address
depletion and scaling in routing. Long-term and short-term solutions
to these problems are being developed.  The short-term solution is
CIDR (Classless InterDomain Routing).  The long-term solutions consist
of various proposals for new internet protocols with larger addresses.
It is possible that CIDR will not be adequate to maintain the IP
Internet until the long-term solutions are in place.  This memo
proposes another short-term solution, address reuse, that complements
CIDR or even makes it unnecessary.

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.
