    Dynamic Host Name lookup?

      Ok, using CF 7.0.0, and I am familiar with cgi scope vars. Especially those that deal with ip of origin.

      I want to be able to "trap" users who are using a specific provider. We have a hacker using a VPN that generates a dynamic IP but the reverse lookup is always the same. Is there way to perform a real time reverse lookup?

      Quick enough to get a fast page load but also maintain a degree of security?

      Perhaps an undocumented CGI var like namelookup(cgi.remote_addr) ?
