zoomkat:
Client/server test code with buttons.
//zoomkat 7-03-12, combined client and server
//simple button GET with iframe code
//for use with IDE 1.0
//open serial monitor and send an g to test client and
//see what the arduino client/server receives
//web page buttons make pin 5 high/low
//use the ' in html instead of " to prevent having to escape the "
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields
//note that the below bug fix may be required

for me,the Eternet Shield im using not is missing the sticker with Mac address on it, What's worse,im living on Campus so i dont have my router but use the internet provided by Uni. In this situation, can i just use the Mac address and IP address .etc. given in your Sketch? or is there any way that i can figure out my own Mac address and IP address?
