How to get a user's client IP address in ASP.NET?

Question

We have Request.UserHostAddress to get the IP address in ASP.NET, but this is usually the user\'s ISP\'s IP address, not exactly the user\'s machine IP address

Answer 1

Try:

using System.Net;

public static string GetIpAddress()  // Get IP Address
{
    string ip = "";     
    IPHostEntry ipEntry = Dns.GetHostEntry(GetCompCode());
    IPAddress[] addr = ipEntry.AddressList;
    ip = addr[2].ToString();
    return ip;
}
public static string GetCompCode()  // Get Computer Name
{   
    string strHostName = "";
    strHostName = Dns.GetHostName();
    return strHostName;
}
