Abstract:
This document describes a mechanism called Public 4over6 which is
designed to provide IPv4 Internet connectivity over an IPv6 access
network using global IPv4 addresses. Public 4over6 was developed in
the IETF and is in use in some existing deployments, but is not
recommended for new deployments. Future deployments of similar
scenarios should use Lightweight 4over6. Public 4over6 follows the
Hub and Spoke softwire model, and uses an IPv4-in-IPv6 tunnel to
forward IPv4 packets over IPv6 access network. The bi-directionality
of the IPv4 communication is achieved by explicitly allocating global
non-shared IPv4 addresses to end users, as well as maintaining IPv4-
IPv6 address binding on the border relay. Public 4over6 aims to
provide uninterrupted IPv4 services to users, like Internet Content
Providers, etc., while an operator makes the transition of the access
network to an IPv6-only access network.
