I may be missing something here but I have to wonder about the usefulness of
the information you will obtain. There is a good chance that someone using
your form for the sake of sending spam has managed to use a "private"
address (10.10.x.x, 192.168.x.x, etc) which will not resolve in DNS to a
domain or host. Also, what if an "anonymizer" service (see
http://anonymizer.com) is used?
