different address from the assigned one.
For IPv6, the guest or namespace is assigned, via SLAAC, the same prefix as the
upstream interface of the host, the same default route as the default route of
the host, and, if a DHCPv6 client is running in the guest or namespace, also the
same address as the upstream address of the host. This means that, with a DHCPv6
client in the guest or namespace, addresses don't need to be translated. Should
the client use a different address, the destination address is translated for
packets going to the guest or to the namespace.
