ethernet shield without arduino board

dumb question: can I, after loading program through usb+mega+ethernet shield, use the ethernet shield stand alone without the mega connected? I saw something like this on sainsmart.


There is a Arduino Ethernet

That is a combination of a Arduino Uno and a Ethernet Shield.

Understand, ...
what are the analog input pins on the ethershield used for. Are they just pass through for the arduino board?

Only pass-through. They are not used.
