For my rating functionality i need to get the User's System(PC) IP address and not the N/W provider IP in c#.
I tried following but not worked:

string host = Dns.GetHostName();
        //IPHostEntry local = Dns.GetHostByName(host);
        //IPAddress ipadd = local.AddressList[0];

C#

string ipAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
        if (ipAddress == null || ipAddress == "")
        {
            ipAddress = Request.ServerVariables["REMOTE_ADDR"];
        }

If you want your external IP address, use an external service:

http://www.whatismyip.com/[^]

Send a get request to the URL above and strip out the IP address, or even get the IP address from the Title of the page:

(?<=<TITLE>.*)\d*\.\d*\.\d*\.\d*(?=</TITLE>)

OK for those who want it:

using System.Net;
using System.Text;

namespace DreamInCode.Snippets
{
    public static class IPFinder
    {
        private static readonly UTF8Encoding utf8 = new UTF8Encoding();

        public static IPAddress ExternalIPAddress
        {
            get
            {
                string whatIsMyIp = "http://automation.whatismyip.com/n09230945.asp";
                WebClient wc = new WebClient();
                string response = utf8.GetString(wc.DownloadData(whatIsMyIp));
                IPAddress myIPAddress = IPAddress.Parse(response);

                return myIPAddress;
            }
        }
    }
}

NOTE: The source page has the OLD automation address - use the snippet above which I have modified to use the new one.

C#

string IP = GetIP();

    public string  GetIP()
    {
        string Str = "";
        Str = System.Net.Dns.GetHostName();
        IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(Str);
        IPAddress[] addr = ipEntry.AddressList;
        return addr[addr.Length - 1].ToString();

    }

Try this --

C#

using System.Net;

string strHostName = string.Empty;
strHostName = Dns.GetHostName();

IPHostEntry ipEntry = Dns.GetHostByName(strHostName);

IPAddress [] addr = ipEntry.AddressList;
for (int i = 0; i < addr.Length; i++)
{
Response.Write("IP Address {0}: {1} " + i + addr[i].ToString() + ", HostName: " + strHostName);
}
