Hey Toke,

For incoming packets, this would be strange behavior, since it's
listening on v4 and v6. For outgoing packets, if wireguard thinks it
should be sending to a v6 address, then that's what it will do. One
way to fix this would be to re-resolve DNS from userspace, which is a
bit ugly. Another way would be to simply store the last v4 address,
and fall back to that if it can't establish a route for the v6
address. And yet another way -- if simplicity is desired -- would be
to do nothing (the status quo), and not build legacy semantics into
something new. Any opinions on this?

Jason
