Yes you can. What you can do on your webserver (I'm assuming apache) is to configure your directory with the ExecCGI directive in your httpd.conf file.

AddHandler cgi-script .cgi
DirectoryIndex index.html index.cgi index.html.var

<Directory "DIR OF CHOICE">
    Options Indexes FollowSymLinks ExecCGI
    AllowOverride none
    Order allow,deny
    Allow from all
</Directory>

Then create an index.cgi file that performs to reference the variable $ENV{'REMOTE_ADDR'} variable within your script. Then utilize that value to perform your task. Lastly, redirect the user to that page. I personally use javascript (because sometimes I refresh multiple iframes or frames) for my redirects, like:

print qq { 
    <script language=javascript>
    window.open('/dir/$ENV{'REMOTE_ADDR'}.html','','')
    </script>
};

Hope this helps
