There is one addition: although the "IPv6 with IPv4-mapped" should work for
all systems that use a dual-stack, some of them do disable the IPv4-mapped
support by default. Thus, it must be enabled. The attached patch does this.
Known default values for this IPv4 mapping:
Linux: on
Windows Vista: off
Side note: all modern system like Linux and Windows Vista (I do not consider
Windows XP to be a modern system) do use a dual-stack for IPv4/6. The
IPv4-mapped-addresses mechanism is system internal and thus unlikely to go
away anytime soon (which is good). I am not sure about the *BSDs, though:
there are various information about them around and all pieces of information
are telling something different.
You can assume a dual-stack if IPV6_V6ONLY is defined, I guess.
This patch is _not_ needed for Linux (it simply won't make a difference).
