With Realm Specific IP [RFC3102]:
This document examines the general framework of Realm Specific IP
(RSIP). RSIP is intended as a alternative to NAT in which the end-
to-end integrity of packets is maintained. We focus on
implementation issues, deployment scenarios, and interaction with
other layer-three protocols.
what is necessary are minor modification on IPv4/transport stack
of new (but not existing) hosts and minor extension of DHCP.
