Technically speaking it is possible to block access to a site using IP
addressing. Pragmatically speaking it is impossible to block access
to a website using such an approach as all the unwanted visitors need
do is use a computer with a different IP address ad infinitum. Thus, it is
a waste of time and effort playing cat and mouse games.
