Any application which is visualizing IPv4 adresses using either
::ffff:x.x.x.x or ::x.x.x.x is wrong(tm). Those addresses should never
ever be shown to the user or used in any way as a textual representation
(that includes for instance logfiles, XML files, and other such things).
Using them for internal storage (thus so that you only need a 128bit
item in your structs) is of course perfectly fine and most likely a
smart thing to do.
If you find an application which does this, don't hesitate to kick the
coders to fix their stuff.

As for the tool do to this, the best tool is the one you will write
yourself and which fully integrates into your existing management setup
(people do have those I hope for them, the point for IT after all is to
make our work less by creating a lot of stuff ;)
