    Default Reverse DNS Lookup

    I would like to know how to get a reverse DNS lookup on an ip address? I am logging my visitors and I would like to show both their ip address and their hostname. I have tried the Request.ServerVariables("REMOTE_HOST") I think it is and all that I get back is the ip address. What am I missing?

    REMOTE_HOST usually returns the IP. Personally I&#039ve never seen it actually return the host name. Check out Browser Hawk for reverse DNS. It&#039ll cost you some jack, but there is a free trial period. Good Luck!
