How can we get the client's IP address in ASP.NET MVC C#?
Every machine on a network has a unique identifier. Just as you would address a letter to send in the mail, computers use the unique identifier to send data to specific computers on a network. Most networks today, including all computers on the internet, use the TCP/IP protocol as the standard for how to communicate on the network. In the TCP/IP protocol, the unique identifier for a computer is called its IP address.
Using HttpRequest.UserHostAddress property
Example
using System.Web.Mvc;
namespace DemoMvcApplication.Controllers{
public class HomeController : Controller{
public string Index(){
string ipAddress = Request.UserHostAddress;
return ipAddress;
}
}
}If we want to fetch IP address outside the controller i.e. in a normal class, we can do like below.
using System.Web;
namespace DemoMvcApplication.Helpers{
public static class DemoHelperClass{
public static string GetIPAddress(){
string ipAddress = HttpContext.Current.Request.UserHostAddress;
return ipAddress;
}
}
}Example using ServerVariables
using System.Web.Mvc;
namespace DemoMvcApplication.Controllers{
public class HomeController : Controller{
public string Index(){
string ipAddress = Request.ServerVariables["REMOTE_ADDR"];
return ipAddress;
}
}
}Output
Since we are running the application locally, the ip address for the localhost is ::1. The name localhost normally resolves to the IPv4 loopback address 127.0.0.1, and to the IPv6 loopback address ::1
