Asp Net Web API 2.1 get client IP address Ask Question

Hello I need get client IP that request some method in web api, I have tried to use this code from here but it always returns server local IP, how to get in correct way ?

HttpContext.Current.Request.UserHostAddress;

from other questions:

public static class HttpRequestMessageExtensions
    {
        private const string HttpContext = "MS_HttpContext";
        private const string RemoteEndpointMessage = "System.ServiceModel.Channels.RemoteEndpointMessageProperty";

        public static string GetClientIpAddress(this HttpRequestMessage request)
        {
            if (request.Properties.ContainsKey(HttpContext))
            {
                dynamic ctx = request.Properties[HttpContext];
                if (ctx != null)
                {
                    return ctx.Request.UserHostAddress;
                }
            }

            if (request.Properties.ContainsKey(RemoteEndpointMessage))
            {
                dynamic remoteEndpoint = request.Properties[RemoteEndpointMessage];
                if (remoteEndpoint != null)
                {
                    return remoteEndpoint.Address;
                }
            }

            return null;
        }
    }

Following link might help you. Here's code from the following link.

reference : getting-the-client-ip-via-asp-net-web-api

using System.Net.Http;
using System.ServiceModel.Channels;
using System.Web;
using System.Web.Http;


namespace Trikks.Controllers.Api
{
    public class IpController : ApiController
    {
          public string GetIp()
          {
                return GetClientIp();
          }

          private string GetClientIp(HttpRequestMessage request = null)
          {
                request = request ?? Request;

                if (request.Properties.ContainsKey("MS_HttpContext"))
                {
                      return   ((HttpContextWrapper)request.Properties["MS_HttpContext"]).Request.UserHostAddress;
                }
                else if (request.Properties.ContainsKey(RemoteEndpointMessageProperty.Name))
                {
                     RemoteEndpointMessageProperty prop = (RemoteEndpointMessageProperty)request.Properties[RemoteEndpointMessageProperty.Name];
                     return prop.Address;
                }
                else if (HttpContext.Current != null)
                {
                    return HttpContext.Current.Request.UserHostAddress;
                }
                else
                {
                      return null;
                }
           }
     }
}

Another way of doing this is below.

reference: how-to-access-the-client-s-ip-address

For web hosted version

string clientAddress = HttpContext.Current.Request.UserHostAddress;

For self hosted

object property;
        Request.Properties.TryGetValue(typeof(RemoteEndpointMessageProperty).FullName, out property);
        RemoteEndpointMessageProperty remoteProperty = property as RemoteEndpointMessageProperty;
