This document specifies a mechanism, the 4rd address mapping, for
service providers to offer residual deployment of the IPv4 service
across IPv6-only domains. Ease of operation and scalability are due
to this address mapping being stateless (no per customer states).
IPv4 address sharing is based on exclusive port sets assigned to
customers, these sets being algorithmically derived from bits used as
port-set identifiers. Features include support of shared IPv4
addresses, same routes for IPv4 as for IPv6, and compatibility with
both provider aggregatable and provider-independent IPv4 prefixes.
The whole 4rd address mapping or part of it can be used combined with
various tunneling and double-translation methods. It can also be
used either alone or in parallel with stateful mechanisms used for
their flexibility where necessary.
