Finding IP Address of site visitor

I'm hopeing someone has encountered this before.  I've used this code to get the IP address of a site visitor before with no problems... now I'm adding it to a site that has a table called "Requests" and I am getting an error "Model.Request does not contain a definition for ServerVariables"  My assumption is that the issue is due to there being a table with the same name.  Is there a way around this or a different method of finding the IP address of a site visitor?


string ip =  Request.ServerVariables["remote_addr"].ToString();

Hi Greg

The following link has some very good information:

Hi Angus,

Thanks for the info.. unfortunately none of the options seem to work in my system due to the fact that I have a table called Requests which conflicts with the code.  There was one part of the page that did work though it returns the IP address of the internal PC, not the external IP that I'm needing.  I did uncover a method that does appear to work...

    private string ExternalIPFinder() {
        try {
            WebClient client = new WebClient();
            // Add a user agent header in case the requested URI contains a query.

            client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR1.0.3705;)");
            string baseurl = "http://checkip.dyndns.org/";
            Stream data = client.OpenRead(baseurl);
            StreamReader reader = new StreamReader(data);
            string IPAddress = reader.ReadToEnd();
            IPAddress = IPAddress
                .Replace("<html><head><title>Current IP Check</title></head><body>", "")
                .Replace("</body></html>", "")
                .Replace("Current IP Address:", "")
                .Replace("\r\n", "").ToString().Trim();

            return IPAddress;
        catch {
            return null;
