Network Address and Port Translation (NAPT) works well for conserving
global addresses and addressing multihoming requirements, because an
IPv4 NAPT router implements three functions: source address
selection, next-hop resolution and optionally DNS resolution. For
IPv6 hosts one approach could be the use of NPTv6. However, NAT
should be avoided, if at all possible, to permit transparent end-to-
end connectivity. In this document, we analyze the use cases of
multihoming. We also describe functional requirements and possible
solutions for multihoming without the use of NAT in IPv6 for hosts
and small IPv6 networks that would otherwise be unable to meet
minimum IPv6 allocation criteria. We conclude that DHCPv6 based
solutions are suitable to solve the multihoming issues, which
described in this document. Nevertheless, we mention that the
possible needs for NPTv6 in the transition phase to the fully
deployment of the proposed solutions.
