How to get the client's ip address in .net standard?

Question

I need to get the client's IP address in .net standard 2.1 class library application.

I am using the code below, It works as expected in the .net framework, but its giving compilation error in .net standard.

private string IPAddress { get { return HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; } }

Error CS1061 'HttpRequest' does not contain a definition for 'ServerVariables' and no accessible extension method 'ServerVariables' accepting a first argument of type 'HttpRequest' could be found (are you missing a using directive or an assembly reference?)

I have used this and works for me:

    public static string GetLocalIpAddress()
    {
        try
        {
            using (var socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, 0))
            {
                socket.Connect("8.8.8.8", 65530);
                var endPoint = socket.LocalEndPoint as IPEndPoint;
                Logger.LogMessage("Local Ip Address detected: " + endPoint.Address.ToString());
                return endPoint.Address.ToString();
            }
        }
        catch (Exception ex)
        {
            Logger.LogMessage(null, "Error obtaining local ip address:" + ex.Message);
            return "";
        }

    }
