    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? <BR><BR>

    I think ( but not certain ) that this needs to be set on the server under IIS Admin. It&#039s a performance hit though.<BR><BR>HTH

    I&#039m about to do this feature very soon with ASP!<BR><BR>I&#039ll just simply strip the data directly from the Network Solutions registrar after passing through an http request. I believe that the syntax "host" will do the trick.<BR><BR>
