Abstract

For service providers to progressively deploy IPv6-only network domains while still offering IPv4 service to customers, the need for a stateless solution, i.e., one where no per-customer state is needed in IPv4-IPv6 gateway nodes of the provider, has been discussed in [Solutions-4v6]. This document specifies one such solution, named "4rd" for IPv4 Residual Deployment. Its distinctive properties are that TCP/UDP IPv4 packets are valid TCP/UDP IPv6 packets during domain traversal and that IPv4 fragmentation rules are fully preserved end to end.

      IPv4 Residual Deployment via IPv6 - A Stateless Solution (4rd)

Abstract

   This document specifies a stateless solution for service providers to    progressively deploy IPv6-only network domains while still offering    IPv4 service to customers.  The solution's distinctive properties are    that TCP/UDP IPv4 packets are valid TCP/UDP IPv6 packets during    domain traversal and that IPv4 fragmentation rules are fully    preserved end to end.  Each customer can be assigned one public IPv4    address, several public IPv4 addresses, or a shared address with a    restricted port set.
