Yes!

I must admit, I was not aware of that option. And its description in
the (3.15) man page seems suboptimal as I probably would have overseen
it even when I looked for it.
But as I see, you even already fixed the documentation to be way more
clear, too. Yay! :-)

That's not that bad IMHO, but yes, might be confusing.

No, that's fine as it is what users would expect. But my comment was
about the compile time (configure) options. (Maybe adding the same for
"fping4" if IPv6 is set as default might be a nice addition.)
Kind regards, Axel
