Yes, what I proposed when the branch was created..

Depends on what you think is easiest for what you think of doing.
If fixing up the existing branch in-place to make sense feels doable
then do so
If it's easier for you to start over from scratch and then bring over
the pieces which make sense from the existing branch then start a new
branch.

Yes.

Yes.

Quite likely.

I would think much of the groundwork of identifying IPv4 dependent parts
has been done already in the current ipv6 branch. So it shouldn't be
much more than implementing the class, and a big search/replace to make
use of it and to fix up a few remaining #ifdefs.
I would suspect doing it in the existing branch is easier as the code
sections needed to be touched is already identified there.. And
hopefully you may find that some of the transition can even be done
incrementally by redefining the macros to make use of the new class but
you know this code better than anyone else around here..
