Find Client Public IP Address Inside Controller of rest web API with out calling external api

Question

I have a web API where I want to capture all incoming request public IP address inside my controller function.

Do you want to get client's IP address from HTTPRequestMessage or from Request? — Prasad Telkikar

I want client internal IP not the hosted IP address , For reference please search whats my IP in google you will get your internal IP address.@Crowcoder — manas sahu

No, that is the public IP. You will never get the internal IP unless the client and server are on the same network. — Crowcoder

Check below code this must return you IP address of client

   protected string GetUser_IP()
    {
        string VisitorsIPAddr = string.Empty;
        if (HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null)
        {
            VisitorsIPAddr = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
        }
        else if (HttpContext.Current.Request.UserHostAddress.Length != 0)
        {
            VisitorsIPAddr = HttpContext.Current.Request.UserHostAddress;
        }
    return VisitorsIPAddr;
    }
