Sorry, no technical answer, just some thoughts on this one.
That would mean, that people voting from their office or from their home
with many people behind one IP-Address (Home-Routers are really cheap
these days). That would not mean one vote per account, but one vote per
company or per home. Since this really isn't unusual it's the question
if you really want it that way.

Just my thoughts,
