a) in most times, isp's wont delegate reverse dns to you, so whatever you
set in your raq's nameserver for reverse dns isn't shown on the net, and
thus, being useless...

b) even if u do have control over reverse dns, your machine will be
contacting other machines only with it's main ip address (unless being
told otherwise, something that you do manually) - so the only reverse dns
you should worry about is the one for your main ip (the ip of the site
that can't be deleted in the GUI)

HTH,
