You get the IP address of the connection by which the client is connecting to your server. If this is within the same network, you won't see a public IP address, because the connection is not routed over the internet.

There are couple of attributes of Request which provides client IP address. Here is the code:

private string GetClientIpAddress (HttpRequestMessage request)
        {
        if ( request.Properties.ContainsKey("MS_HttpContext") )
            {
            return ((HttpContextWrapper) request.Properties["MS_HttpContext"]).Request.UserHostAddress;
            }
        if ( request.Properties.ContainsKey(RemoteEndpointMessageProperty.Name) )
            {
            var prop = (RemoteEndpointMessageProperty) request.Properties[RemoteEndpointMessageProperty.Name];
            return prop.Address;
            }

        if ( request.Headers.Contains("X-Forwarded-For") )
            {
            return request.Headers.GetValues("X-Forwarded-For").FirstOrDefault();
            }

        // Self-hosting using Owin. Add below code if you are using Owin communication listener
        if ( request.Properties.ContainsKey("MS_OwinContext") )
            {
            var owinContext = (OwinContext) request.Properties["MS_OwinContext"];
            if ( owinContext?.Request != null )
                {
                return owinContext.Request.RemoteIpAddress;
                }
            }

        if ( HttpContext.Current != null )
            {
            return HttpContext.Current.Request.UserHostAddress;
            }

        return null;

        }

Hope it will work. ~Prasad
