bitsoft ShowIP will also show us the gateway that we are connected to (a telecommunication net component). We can also do pings in case we need to know if another computer is turned on and connected to the Internet.
Furthermore, this application allows the user to copy this data to the clipboard, in case we need it in any other application.
As an option, we can configure the refresh time of this data, because even though its doesn't generally change very often, it can happen that they can change and we have to know them exactly all the time.
All in all, a very simple application that will avoid us having to write some console line or investigate in various configuration menus to find out these details.
