Technical Summary

   When a private network or internetwork grows very large it is
   sometimes not possible to address all interfaces using private IPv4
   address space because there are not enough addresses.  This document
   describes the problems faced by those networks, the available options
   and the issues involved in assigning a new block of private IPv4
   address space.

   While this informational document does not make a recommendation for
   action, it documents the issues surrounding the various options that
   have been considered.

However, it is also well understood that cascading NAT deployments in the existing private address space will cause different types of severe problems when address spaces overlap. At this point there is no clear agreement of the likelihood of various problems or the respective trade-offs."
