IESG Note

   The IESG notes that the set of documents describing the RSIP
   technology imply significant host and gateway changes for a complete
   implementation.  In addition, the floating of port numbers can cause
   problems for some applications, preventing an RSIP-enabled host from
   interoperating transparently with existing applications in some cases
   (e.g., IPsec).  Finally, there may be significant operational
   complexities associated with using RSIP.  Some of these and other
   complications are outlined in section 6 of the RFC 3102, as well as
   in the Appendices of RFC 3104.  Accordingly, the costs and benefits
   of using RSIP should be carefully weighed against other means of
   relieving address shortage.

Abstract

   This document presents a protocol with which to implement Realm
   Specific IP (RSIP).  The protocol defined herein allows negotiation
   of resources between an RSIP host and gateway, so that the host can
   lease some of the gateway's addressing parameters in order to
   establish a global network presence.  This protocol is designed to
   operate on the application layer and to use its own TCP or UDP port.
   In particular, the protocol allows a gateway to allocate addressing
   and control parameters to a host such that a flow policy can be
   enforced at the gateway.
